Answer:
Explanation:
Block A sits on block B and force is applied on block A . Block A will experience two forces 1) force P and 2 ) friction force in opposite direction of motion . Block B will experience one force that is force of friction in the direction of motion .
Let force on block A be P . friction force on it will be equal to kinetic friction, that is μ mg , where μ is coefficient of friction and m is mass of block A
friction force = .4 x 2.5 x 9.8
= 9.8 N
net force on block A = P - 9.8
acceleration = ( P - 9.8 ) / 2.5
force on block B = 9.8
acceleration = force / mass
= 9.8 / 6
for common acceleration
( P - 9.8 ) / 2.5 = 9.8 / 6
( P - 9.8 ) / 2.5 = 1.63333
P = 13.88 N .
Answer
hawk maintains a consistent internal temperature in both the heat of the day and the cool of night this is called as endothermy.
Endothermy also known as warm-bloodedness is defined as the ability of an animal, bird or organism to produce heat and conserve it to maintain a consistent internal temperature.
Answer:
C
Explanation:
gravity is a pulling force according to Newton
It depends on the tempature of something or an object,
The Object has to go from hot to cold, that is a primary example of how heat transfer occurs
