Answer:
so, net force acting on the object is 121.2 Newton.
Explanation:
net force acting on it =
gravitational force acting on it - air resistance.
so, gravitational force ( g ) = mass × acceleration
( 9.8 is acceleration due to gravity )
force acting due to air resistance = 137.2 - 16
Answer:
Temperature is a measure of the average kinetic energy of the particles. Temperature is a measure of how hot or cold something is. Temperature is not the same thing as heat.
Explanation:
Power is the rate at which work is done (2nd option)
It will take 20 seconds for the car to attain a speed of 34 m/s
Explanation:
- Acceleration of an object is given by a = velocity/time.
- Here, acceleration of the car = 1.7 m/s² and velocity = 34 m/s. Using these, find time.
- Time = velocity/acceleration
= 34/1.7 = 20 s
So it takes 20 seconds to attain a speed of 34 m/s
Answer:
Your answer is: K.E = 8.3 J
Explanation:
If the height (h) = 169.2 meters (m) and the mass (m) is 0.005 kilograms (kg) the total energy will be kinetic energy which is equal to the potential energy.
K.E = P.E and also P.E equals to mgh
Then you substitute all the parameters into the formula ↓
P.E = 0.005 × 9.81 × 169.2
P.E = 8.2908 J
So your answer is 8.2908 but if you round it is K.E = 8.3
