Yes. because if there is a direction taken positive and the object is accelerating negatively it can bounce of a wall and change its direction so through an obstruction can it do that
Answer:
It gives our light which we need for probably everything.
Explanation:
Answer:
1681714.28571 N/C
Yes it could exist
Explanation:
m = Mass of housefly = 12 m
q = Charge = 70 pC
g = Acceleration due to gravity = 9.81 m/s²
E = Electric field
When an object accumulates charge it means that it is gaining electrons making it negatively charged. This is the concept of static electricity.
Here, the electric force and the graviational force will balance each other
1681714.28571 N/C of electric field would be required to levitate
The direction of the electric field would be upwards vertically.
In air the critical value of electric field is 
which is more than the critical value of electric field in air. So, the electric field can exist.
Explanation:
Edothermic process is the absorbtion of heat.
It is the opposite of exothermic process which is the release of energy. In edothermic process thermal energy is absorbed from the surrounding
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 .
