A 100kg man wants to burn off 500 kilocalories by running up ar elliptical. How far will he have to climb?
The distance the 100kg man must climb to burn off 500 kilocalories by running up an elliptical path is 2,136.1 m.
Potential energy of the man
The potential energy of the man from a known height can be used to deternine the distance the man would have to climb.
P.E = mgh
Where;
P.E is potential energy, given as 500 kilocalories,
1 kcal = 4186.8 joules
500 kcal = 2,093,400 J

ball and bowl system
Answer:
Once the ball is place at the position A and then released, It will accelerate towards the mean position under its weight. At the mean piston it again maximum velocity and momentum so its moves up-to the position B due to inertia. At B it has zero velocity so zero kinetic energy but maximum potential energy.
Again from point B it will move towards O under the restoring Force having maximum velocity at O but does not stop at O due to inertia and will go up to A. In this way the ball will continue to oscillate between the points A and B about the point O, it has simple harmonic motion.

When constructive interference happens between two sound waves, the sound will get louder. What does this tell you about the relationship between amplitude and volume of sound?
Answer:
If the amplitude increases the volume increases and vice versa.So therefor the volume depends on how high or low the amplitude is.
When two or more sound waves occupy the same space, they affect one another. The waves do not bounce off of each, but they move through each other. The resulting wave depends on how the waves line up.
With constructive interference, two waves with the same frequency and amplitude line up – the peaks line up with peaks and troughs with troughs as in diagram A above. The result is a wave that has twice the amplitude of the original waves so the sound wave will be twice as loud.

Blowing up a balloon and letting it go is an example of newton’s.
Answer:
Third Law Of Motion
Explanation:
When we let go of the end, the air rushes out and pushes against the air around the balloon to move it in the opposite direction. Newton describes this effect in his third law.
The blowing up of a balloon and letting it go is an example of newton's third law of motion or action-reaction law.
What is newton's third law?According to Newton's third law, when two bodies come into contact, they exert forces on one another that really are equal in strength and pointed in the opposite direction. The third law is frequently referred to as the law of actions and consequences.
This law applies to bodies in constant or rapid motion and is crucial for understanding problems of static balance, where all forces are in balance. It doesn't only use bookkeeping techniques; the forces it portrays are actual forces. A book laying on a table, for instance, exerts a downwards force equal to its weight on the table. The third law states that the book is subjected to an equal and opposing force from the table.

Water is flowing through a pipe with a velocity of 5 m/s. The pipe has a diameter of 6 cm. The pipe then goes up 3 meters and narrows to a diameter of 4 cm. If the gauge pressure in the lower part of the pipe is 80 kPa, what is the gauge pressure in the higher and more narrow part of the pipe
The gauge pressure in the higher part will be 136 kph. The pressure is found with the help of the Bernoulli equation.
What is gauge pressure?The difference between absolute pressure and atmospheric pressure is known as gauge pressure. Relative pressure is another name for gauge pressure.
From the continuity equation;
[tex]\rm A_1v_1=A_2v_2 \\\\ \rm \frac{\pi}{4}(6)^2 \times 5 = \frac{\pi}{4}(3)^2 v_2 \\\\ v_1 = 20 \ m/sec[/tex]
The gauges pressure in the higher part is found as;
From the Bernoullis equation;
[tex]\rm \frac{P_1}{\rho g} + \frac{v_1^2}{2g} +Z_1 = \frac{P_2}{\rho g} + \frac{v_2^2}{2g} +Z_2 \\\\ \frac{80 \times 10^3 }{\rho g} + \frac{(5)^2}{2g} +0= \frac{p_2}{\rho g} + \frac{(20)^2}{2g} +3 \\\\ \frac{80 \times 10^3 - P_2 }{1000 \times 9.81 } = \frac{20^2-5^2}{2 \times 9.81 } +3 \\\\ P_2 = 136 \ kpa[/tex]

A geyser has a rating 2 kVA, 240 V. (a) what is the electrical energy consumed by it in (i) kWh and (ii) joule if it is used for 90 mins. (b) if the cost of electricity is rupees 4.50 per commercial unit find the cost.
See below~
Explanation:
Given, P = 2 kVA = 2 kW,
t = 90 min = 1.5 h
(a) (i) Electrical Energy Consumed = power * time
= 2 kW x 1.5 h
= 3 kWh ( or 3 commercial unit)
(ii) Since 1 kW = 3.6 x 10^6 J
therefore,
Electrical energy consumed = 3 x 3.6 x 10^6 J
= 1.08 x 10^7 J
(b) Cost of electricity
= energy consumed in kWh x cost per kWh
= 3 x Rs 4.50 = Rs. 13.50
