answer:
1.When an electric current is passed through a conductor, the conductor becomes hot after some time and produce heat. This happens due to the conversion of some electric energy passing through the conductor into heat energy. This effect of electric current is called heating effect of current.
2.As per the law of combination of resistances in series,
R=R1 +R2 +R3+R4+R5
R=0.2+0.2+0.2+0.2+0.2
=1ohm
3.power is amount of electrical energy consumed per unit time. Amount of power consumed in a device is proportional to the current flowing in the device. The unit of electric power is watt.

The equivalent formulas for velocity, acceleration, and force using the relationships covered for UCM, Newton’s Laws, and Gravitation.
We know that,
Velocity :
The velocity is equal to the rate of position of the object.

Newton’s second Laws
The force is equal to the change in momentum.
In mathematically,
[tex]F=\dfrac{d(p)}{dt}[/tex]
Put the value of p
[tex]F=\dfrac{d(mv)}{dt}[/tex]
[tex]F=m\dfrac{dv}{dt}[/tex]
Put the value from equation (II)
[tex]F=ma[/tex]
This is newton’s second laws.
Gravitational force :
The force is equal to the product of mass of objects and divided by square of distance.
In mathematically,
[tex]F=\dfrac{Gm_{1}m_{2}}{r^2}[/tex]
Where, m₁₂ = mass of first object
m= mass of second object
r = distance between both objects
Hence, The newton’s second law is F=ma

Alice and Tom dive from an overhang into the lake below. Tom simply drops straight down from the edge, but Alice takes a running start and jumps with an initial horizontal velocity of 25 m/s. Neither person experiences any significant air resistance. Just as they reach the lake below,
Answers
Answer:
The velocity of Alice (25 m/s) will be greater than that of Tom (0), when they reach the lake below.
Explanation:
Given;
initial horizontal velocity of Tom is zero since he dropped straight down from the edge.
initial horizontal velocity of Alice is 25 m/s.
Their respective horizontal velocity when they jumped is the same as when they reach the lake below.
If we compare their velocities when they reach the lake, one will be greater than the other, if we neglect air resistance.
Thus, the velocity of Alice (25 m/s) will be greater than that of Tom (0), when they reach the lake below.

What is the displacement of the ride between 0s and 16 s?
Answers
Answer:
See attached answer.
Explanation:
To solve this we must be knowing each and every concept related to displacement and its calculations. Therefore, the ride's displacement from time t = 0 s to time t = 16 s is 16v.
What is displacement?The distance along a straight line connecting an object's original and final positions is its displacement [x].
Displacements are not always a good thing. It may also be 0 or negative. A negative displacement indicates that the item has moved away from the origin and toward the right if a positive direction is situated to the right of both the origin.
If the body's velocity at a given moment in time is 'v' m/s, then displacement may be expressed mathematically as-
v = dx /dt
dx = vdt
Integrating on both sides, we get
∫dx = ∫vdt
∫dx [x = 0 to x = x] = ∫vdt [ t = 0 to t = 16 s]
x = v [16 - 0]
x = 16v
Therefore, the ride's displacement from time t = 0 s to time t = 16 s is 16v.

What is Speed? the ability to rest the ability to rest the ability to minimize the time cycle of a given movement the ability to minimize the time cycle of a given movement the ability to apply force the ability to apply force the ability to use oxygen?
Answers
Answer:
Speed is a scalar quantity that refers to "how fast an object is moving." Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a short amount of time.
Explanation:
The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time.

2. 0.5 m/s
3. 1 m/s
4. 1.5 m/s
5. 3 m/s
6. 30 m/s

Answer:
3.0m/s so it’s number 5
Explanation:
The magnitude of the player's average velocity during the drill is 0 m/s.
The given parameters;
length of the court, L = 30 mnumber of times, = 3time of motion, t = 60 sAverage velocity is change in displacement per change in time of motion.
[tex]\Delta \bar v = \frac{\Delta x}{\Delta t}[/tex]
where;
[tex]\Delta x[/tex] is the change in displacementThe change displacement is zero, since the player moved forward and back to the exact initial position.
[tex]\Delta \bar v = \frac{3(30) - 3(30) }{60} = 0[/tex]
Thus, the magnitude of the player's average velocity during the drill is 0 m/s.

the correct symbol for the metric (SI) unit of temperature is
A: k
B: t
C: f
D: c
Answers
C (Celsius) is the correct symbol for the metric (SI) unit of temperature. The correct option is D.
The Celsius scale is widely used for measuring temperature in the metric system.
The symbol "°C" is used to represent degrees Celsius. It is named after the Swedish astronomer Anders Celsius, who introduced the scale in the 18th century.On the Celsius scale, the freezing point of water is defined as 0 degrees Celsius, and the boiling point of water is defined as 100 degrees Celsius at standard atmospheric pressure.The Celsius scale is an integral part of the International System of Units (SI), which is the modern metric system used for scientific and everyday measurements.In certain scientific and engineering fields, such as thermodynamics, the Kelvin scale (symbol: K) is also used as an absolute temperature scale but the SI unit of temperature is Celsius.
Thus, the correct option is D.
