Answer:
D
Explanation:
The object will remain motionless(i just need points)
Answer:
A
Explanation:
the string would be dangling backwards because you are moving forward it would be putting backward force on the string
Answer:
A 60 kg person standing on a platform at the surface of Saturn and they jumped, they would have to push with a force greater than 540 N
Explanation:
The gravitational attraction between an object on the surface of a planet and the planet is given by the weight of the object
Therefore the force needed to be applied for an object to lift off the surface of a planet = The weight of the object
The weight of the object on the surface of a planet = m × g
Where;
m = The mass of the object
g = The strength of gravity on the planet's surface in N/kg
The given parameters are;
The mass of the person standing on a platform at the surface of Saturn, m = 60 kg
The strength of gravity on the surface of Saturn = 9 N/kg
Therefore, we have;
The weight of the person = The force greater than which the person would have to push on the surface of Saturn so as to Jump = The weight of the person on the surface of Saturn = 60 kg × 9 N/kg = 540 N
Therefore, for a 60 kg person standing on a platform at the surface of Saturn and they jumped, they would have to push with a force greater than 540 N.
Answer:
The charge on point A is = 2.4 × C
The charge on point B is = 1.2 × C
Explanation:
Given data
Distance (r) = 0.19 m
Magnitude of the charge on A is twice that of the charge on B i.e.
F = 46 N
We know that force between the charges is given by
= 1.2 × C
= 2 ×
= 2 × 1.2 ×
= 2.4 × C
Therefore the charge on point A is = 2.4 × C
The charge on point B is = 1.2 × C
