B) How well does your result in part (a) agree with your friends theoretical prediction that a=0. 13 +/- 0. 01m/s^2

Answers

Answer 1

0.08 m/s2 is the average acceleration. The acceleration's degree of uncertainty is 0.0135 m/s2.

Describe acceleration.

Accelerations are included in vector quantities. An object's acceleration in relation to a net force is determined by the direction of that force. Force imbalances lead to acceleration in a body.

Uniform, non-uniform, and average acceleration are the three primary types of accelerated motions. It is said to have uniform acceleration when an object moves in a straight line with an increase in speed that happens at regular intervals of time.

Acceleration is the term used to describe any change in the speed or direction of a motion. Anything that is accelerating is moving faster, slower, or in a direction other than straight forward.

If an object was traveling horizontally off a cliff at 9 m/s for 7 seconds, how far did it go?

Answers

The object travelled 63 meters at 9m/s for 7 seconds.

What is distance travelled?

The length of the trajectory taken between the initial and final positions of the moving body is the distance traveled.

To calculate the distance traveled by an object traveling horizontally off a cliff, you can use the formula:

d = v * t

where d is the distance traveled, v is the velocity (9 m/s), and t is the time (7 seconds).

By substituting the given values into the formula, we get:

d = 9 * 7 = 63 meters

So, the object traveled 63 meters horizontally before it hit the ground after being launched off the cliff at 9 m/s for 7 seconds.

What is the formula of 3 law of motion?

Answers

The three laws of motion, as described by Sir Isaac Newton, are as follows:

Every object in a state of uniform motion will remain in that state of motion unless an external force acts on it. This is known as the law of inertia.

The force acting on an object is equal to the mass of that object multiplied by its acceleration. This is known as Newton's second law of motion, and is often represented by the equation F = ma.

For every action, there is an equal and opposite reaction. This is known as Newton's third law of motion.

Newton's laws of motion are fundamental principles that describe the physical behavior of objects in motion. The first law, the law of inertia, states that an object at rest will remain at rest, and an object in motion will continue in motion with a constant velocity, unless acted upon by a net external force. The second law of motion, states that the acceleration of an object is directly proportional to the net force acting on the object, and inversely proportional to its mass. The third law states that for every action there is an equal and opposite reaction.

The Sun's path, as viewed from the equator, is highest in the sky on _____. A) the spring and fall equinoxes B) the winter solstice. C) the summer solstice D) the day when Earth is closest to the Sun

Answers

The correct option is A, the Sun's path, as viewed from the equator, is highest in the sky on the spring and fall equinoxes.

Fall equinox is an astronomical event that marks the transition from summer to autumn in the Northern Hemisphere and from winter to spring in the Southern Hemisphere. On the day of the fall equinox, the sun rises directly in the east and sets directly in the west. This marks the end of the summer season and the beginning of the autumn season. During the fall equinox, all areas of the Earth experience nearly the same amount of daylight and darkness.  

The fall equinox occurs in the middle of September in the Northern Hemisphere and in the middle of March in the Southern Hemisphere. It is the first day of autumn and the last day of summer in the Northern Hemisphere and the first day of spring and the last day of winter in the Southern Hemisphere.

The fall equinox marks the return of balance after the summer solstice, during which the days are the longest and the nights are the shortest. During the fall equinox, the day and night are of equal length and the sun is directly over the equator. After the fall equinox, the days become gradually shorter and the nights become gradually longer.

If 400g of ice at -2°C i placed in 1 kg of water at 21°C what i the end product when equilibrium i reached?

Answers

The end product when equilibrium is reached is a mixture of water and ice at a temperature of 0°C.

Since the temperature of the water is higher than the temperature of the ice, the ice starts to melt and the temperature of the mixture decreases until it reaches the freezing point of 0°C.

The amount of water in the mixture increases due to the melting of the ice while the amount of ice decreases until all of the ice has melted and there is 1.4 kg of water in the mixture.

What is a force?

The word 'force' has a precise meaning. At this level, it is completely appropriate to describe a force as a push or a pull. A force is not something that an object contains or 'has in it'.

Calculation -:

In  ∑F=m rv 2,

both m and r are unknown but remain constant.

Symbolically,

write ∑F slow​ =( r m​ )(14.0m/s) 2  

and ∑F fast​ =( r m​ )(18.0m/s) 2

Therefore, ∑F is proportional to v 2  and increases by a factor of ( 14.018.0​ ) 2  

as v increases from 14.0m/s to 18.0m/s.

The total force at the higher speed is then

What is resultant force?

In physics and engineering, a resultant force is a single force and associated torque obtained by combining a system of forces and torques acting on a rigid body by vector addition. The characteristic of a resultant force or force-torque is that it has the same effect on a rigid body as the original force system. The resulting forces on the body are calculated and visualized by computational analysis or (for sufficiently simple systems) by free-body diagrams.

For A and B:

Since net force is zero the applied forces in all four direction will be equal but opposite.

So A will be 50 N and B will be 200 N.

For C:

The net force is 900 N;

C = 900 + 200

C = 1100 N

For D and E:

The net force is 60 N left; this means the net upward or downward force acting on the object is zero.

So E = 300 N

D = 80 - 60

D = 20 N

For F, G and H:

The net force is 30 N right; this means the net upward or downward force acting on the object is zero.

So F and H will be zero.

G = 20 + 30

G = 50 N

With the Sun and Moon in this position, what does the side of the earth facing the moon experience? ft Select one O A a normal high tide B. a neap high tide C. a spring high tide D. a spring low tide a neap low tide F a normal low tide age

Answers

With the Sun and Moon in this position, the side of the earth facing the moon experiences a spring high tide. Thus Option C is the answer.

A spring tide is a tide that occurs when the gravitational pull of the Moon and the Sun are in alignment. During a new moon or full moon phase, the gravitational pull of the Moon and the Sun combine to produce stronger than normal high tides and stronger than normal low tides. The term "spring tide" does not refer to the season of spring, but rather the tide's "springing forth" of water.

During a spring tide, the difference between high tide and low tide is at its greatest, and the water level rises higher and falls lower than during a neap tide. This is because the gravitational pull of the Moon and Sun are working together to produce the tide, rather than against each other. This results in a high tide that is higher than a normal high tide, referred to as a spring high tide.

It is important to note that spring tides occur twice a month, around the time of the new and full moon, when the Moon and Sun are in alignment.

Eileen is holding a pillow with a mass of 0.30 kg when Stephanie decides she wants it and tries to pull it way from Eileen. If Stephanie pulls horizontally on the pillow with a force of 10.0 N and Eileen pulls with a horizontal force of 11.0 N, what is the magnitude of the net acceleration of the pillow

Answers

The magnitude of the net acceleration of the pillow is 3.333 m/s^2 .

How do you determine the magnitude of the net acceleration?

To determine the magnitude of the net acceleration of the pillow, we can use Newton's Second Law of Motion, which states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration:

Fnet = ma

where

Fnet = net force acting on the pillow

m = mass of the pillow (0.30 kg)

a = acceleration of the pillow

Fnet = FStephanie - FEileen = 10 N - 11 N = -1 N

So, the net force acting on the pillow is -1N

Now, we can use Newton's Second law to find the acceleration of the pillow

a = Fnet/m = -1 N / 0.3 kg = -3.333 m/s^2

Therefore, the magnitude of the net acceleration of the pillow is 3.333 m/s^2 .

What do you mean by force of gravity?

The attraction between two objects in the cosmos is created by the force of gravity. Objects fall towards the center of the earth as a result of this force, which also keeps planets and moons in their orbits around stars. The mass of the objects and the separation between their centers of mass determine how much gravity there is between them.

The force of gravity between two objects is:

F = G * m1 * m2 / r^2

Where F  = force of gravity,

G = gravitational constant (approximately 6.67 x 10^-11 N*(m/kg)^2),

mass m1 and mass m2 are the masses of the objects,

r = distance between their centers of mass.

Given:

the mass of the newborn baby = 2.50 kg,

the mass of the doctor = 80.0 kg,

the distance between them = 0.250 m,

F = (6.67 x 10^-11 N*(m/kg)^2) * (2.50 kg) *(80.0 kg) / (0.250 m)^2
