Bond breaking is endothermic.
Bond formation is exothermic.
Answer:
The force exerted by the ball on the bat has a magnitude of 100 N and its direction is exactly opposite to that of the force exerted by the bat on the ball.
Explanation:
Recall that Newton's third law tells us that : "For every action, there is an equal and opposite reaction."
Therefore if the bat acts on the ball with a force of 100 N, the ball acts on the bat with a similar magnitude of force (100 N) but direction opposite to the original force.
Answer:
It remains constant
Explanation:
As we know that buoyant force on an object given as
Fb = ρ Vd g
ρ= Density of fluid
Vd=Volume displace by body
g=10 m/s²
Fb =buoyant force
So from above we can say that buoyant force does not depends on the depth. It only depends on the fluid density and volume displace by body.
So when rock gets deeper and deeper the buoyant force will remain constant.
It remains constant
Answer:
a) Fg = m* g
b) Fg = 58.86 N
c) pointing down (towards the center of the Earth)
d) N = 58.86 N
e) pointing up
Explanation:
a) Force is defined as mass of the object times the acceleration it is subjected to. In our case, the block is subjected to the acceleration of gravity (g), therefore the force due to gravity (Fg) is Fg=m*g
b) perform the indicated product of part a):
Fg = m*g = 6 kg * 9.81 m/s^2 = 58.86 N
c) since the object is not moving, that means that the contact force exerted by the surface were the block is resting, must equal the acting force of gravity, but pointing in opposite direction, so the NET force on the block is zero. Therefore, the magnitude of the normal force (N) must equal the magnitude of the object's weight: N = 58.86 N
d) As explained in part c), the normal force must be acting in opposite direction to the force of gravity, which means pointing up.
