Answer:
Can a room be gravitationally shielded? No, it can't.
Explanation:
the room cannot be gravitationally shielded because there is only one gravitational charge, in this case is mass. Mass can always be positive. the room can be electrically shielded because there are two type of charge, positive and negative charge than can cancel each other out.
Answer:
0.00098 N
Explanation:
The weight of an object is given by:
where
m is the mass of the object
g is the gravitational acceleration on the planet
In this problem, we have:
is the mass of the honeybee
is the acceleration due to gravity
Substituting into the equation, we find:
Answer:
The car would speed off 2x's as fast as the speed of the heavy truck provided the the collision is an elastic collision where there's no or little friction occurring within the scenario.
Explanation:
Newton's law proves that an object with a greater mass can move objects of lesser mass at greater distances and speed.
Answer:
speed is 4/3 × g × sin β
acceleration is g sin θ
Explanation:
Given data
mass = M
radius = R
distance = s
angle = β
to find out
final speed and the acceleration
solution
we know that cylinder is rolling on inclined plane
so from conservation of mechanical energy
energy at top = energy at bottom
energy at top will be
= m ×g×h
= m ×g×s sinβ ................1
and
energy at bottom will be
= 1/2 ×m × v² + 1/2 × z × ω²
= 1/2 ×m × v² + 1/2 × 1/2 ×m× r² × (v/r)²
= 3/4 × v² .................2
equating now equation 1 and 2
m ×g×s sinβ = 3/4 × v²
so v = 4/3 × g × sin β
so speed is 4/3 × g × sin β
and acceleration is
= mg sin θ ............3
and
acceleration = ma ............4
now equation equation 3 and 4
ma = mg sin θ
so acceleration is g sin θ
I think it means that your putting in an equal amount of force on each hand because it's the same brain that controls what you do. I think that's what it means, not entirely sure but hope this helps
