A battery powering a flashlight is the correct answer
The total mechanical energy is
Explanation:
The total mechanical energy (TME) of an object is equal to the sum of its gravitational potential energy (U) and its kinetic energy (K):
When the car is at rest 50 m above the ground, its speed is zero, therefore its kinetic energy is zero as well:
K = 0
This means that the TME is just equal to the gravitational potential energy:
where:
m is the mass of the car
is the acceleration of gravity
h is the height above the ground
For the car in the problem,
m = 575 kg
h = 50 m
Substituting,

Answer:
5.3×10⁴ m/s
Explanation:
From the question,
Momentum = mass× velocity
M = mV................ Equation 1
Where M = momentum of the airplane, m = mass of the airplane, V = Velocity of the airplane
make V the subject of the equation
V = M/m.................. Equation 2
Given: M = 1.6×10⁹ Kg.m/s, m = 3.0×10⁴ kg
Substitute these values into equation 2
V = 1.6×10⁹/3.0×10⁴
V = 5.3×10⁴ m/s
The purpose of an air filter is to purify the air around you removing particles such as dust from the air.
Answer:
It would be 2600
Explanation:
M/S stands for meters per second. If it moved 1 meter for 2600 seconds, than it would be 2600. You just multiply 2600 by 1! I hope this helps :D
