It would be true because <span>In physics, the </span>kinetic energy<span> of an object is the </span>energy<span> that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this </span>energy<span> during its acceleration, the body maintains this </span>kinetic energy<span> unless its speed changes.</span>
Answer:
750 miles / hour
Explanation:
velocity = distance / time
= 4500 miles / 6 hours
= 750 miles / hour
Answer:
Answer: 18.3 km/s
Explanation:
If a satellite in Molniya orbit has an apogee at 48.000 km as measured from the center of Earth, and a velocity of 3.7 km/s. Its velocity in at perigee would be 18.3 km/s.
A = horizontal displacement of the humming bird = 1.2 m
B = vertical displacement of the humming bird = 1.4 m
C = net displacement of the humming bird from initial to final position = ?
In the triangle drawn , Using Pythagorean theorem
C = √(A² + B²)
inserting the values
C = √(1.2² + 1.4²)
C = √(1.44 + 1.96)
C = √(3.4)
C = 1.4 m
Hence the net displacement of hummingbird comes out to be 1.4 m
The answer is D. The input force is equal to the output force.
I just did test and got it right
