Answer:
Explanation:
a ) maximum friction possible
= .3 x 30 x 9.8
= 88.2 N
It is friction force which creates acceleration in 30 kg packing case.
Friction force F
F = ma
= 30 x 2.51
= 75.3 N
It will be in north direction , the direction of acceleration.
b ) F = ma
= 30 x 3.63
= 108.9 N
But maximum friction force is 75.3 N , so load will start slipping northward. so friction force will be acting southward.
Friction force = .2 x 30 x 9.8 ( coefficient of kinetic friction applies )
= 58.8 N
towards south .
Answer
given,
height = 300 m
speed of aircraft = 40 m/s
propeller rotation = 20 rev/s
moment of inertia = I = 70 Kg/m²
mass = 200 Kg
since no non conservative force act on system, the mechanical energy is conserved after propeller fall off.
by conservation of energy
as there is no air resistance ωi = ωf
b) the rotation rate of the propeller remains same as there is no air resistance.
Answer:
Our modern ideas about government were influenced by many different ideas and traditions. The biggest influence came from their British heritage. (Remember the colonists WERE British until the American Revolution!)
Answer:
4. deducing and applying natural laws
Answer:
The pressure will increase
Explanation:
Gay-
Lussac's Law states that the pressure of a
given mass of gas is directly proportional to the
absolute temperature of the gas, provided
volume is kept constant.
