Answer:
New acceleration is 20.0 m/s².
Explanation:
F = m*a
F = 0.35 kg * 10.0m/s²
If Force will be doubled , and mass will be the same
we can write
2F = 2*0.35 kg*10.0 m/s²=0.35kg*20.0m/s²
New acceleration is 20.0 m/s².
According to Einstein's Theory of Relativity, an object at rest experiences the time differently from an object moving: a moving clock would be slower than a resting clock.
Two objects experiencing the same acceleration, do experience the same time dilation, therefore a person on Earth's surface experiencing a gravitational acceleration of 9.8m/s² will feel the same effects of a person on a spaceship accelerating at 9.8m/s².
Hence, the correct answer is: <span>D) Acceleration in space and gravity on Earth have the same effects on objects.

Answer:. 1008
7×9= 63 square meters total area.
Each square meter is 100 cm wide and 100 cm long. 100÷25 = 4, so it will take 4 tiles wide and 4 tiles long for each square meter. 4×4= 16
Multiply 16 × 63 = 1008 tiles needed.
Explanation:
The acceleration of the car in SI units is <u>2.68m/s².</u>
The acceleration is <u>0.27</u> times the acceleration due to gravity g.
Convert the speed in mph into m/s.
1 mile = 1609 m and 1h = 3600 s.
Therefore,
Acceleration is the rate of change of velocity. The car starts from rest , its initial velocity u = 0 and accelerates to a velocity v of 26.82 m/s in 10 s.
Use these values in the equation and calculate the acceleration.
Thus the car accelerates at a rate of <u>2.68 m/s².</u>
The acceleration due to gravity g on Earth has a value 9.81 m/s².
Find the ratio
The car's acceleration is <u>0.27 times the value of g.</u>
