Answer:
a)0.22 m/s².
Explanation:
Given that
Net force ,F= 6.8 N
mass ,m = 31 kg
From the second law of Newton's
F = m a ---------------1
Where
F=Net force ,m=mass
a=Acceleration
Now by putting the values in the equation 1
F = m a
6.8 = 31 x a
Therefore the acceleration of the scooter will be 0.22 m/s².
The answer will be "a".
a)0.22 m/s².
Answer:
4
Explanation:
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
= Mass of Earth
= Mass of Moon
r = Distance between Earth and Moon
Old gravitational force
New gravitational force
Dividing the equations
The ratio is
The new force would be 4 times the old force
Answer:
false
Explanation:
The car would not move unless being pushed or dragged
Since the man and the walkway has velocity (which is a vector) moving in the same direction, who would add the velocities together.
That means the relative velocity would be 2 m/s to the East
If you picture it in your mind, imagine walking down an escalator, you feel like you're moving faster than you really are.
In a different example, if the man was moving 0.9 m/s to the West, they are moving in opposite directions, which means you would subtract the 2 velocities.
Answer:
Gravity
because it's factorised by mass of a body.
For other forces, they deal with charges of negligible mass and weights
