Answer:
C is the correct answer and i hope ur having a good day UwU
Explanation:
Answer:
a. 1.75 Nm²/C
b. Yes.
Explanation:
a. Electric Flux is given as:
Φ = E*A*cosθ
Where E = electric flux
A = Surface area
Φ = 14 * 0.25 * cos60
Φ = 1.75 Nm²/C
b. Yes, the shape of the sheet will affect the Flux through it. This is because flux is dependent on area of the surface and the area is dependent on the shape of the surface.
Answer:
Mass , momentum and mechanical energy
Explanation:
There are two types of collision.
1. Elastic collision: in case of elastic collision no energy is loss in form of heat and sound .
The momentum and the kinetic energy is conserved.
2. Inelastic collision: in case of inelastic or partially elastic collision, some of energy is lost in form of heat or sound. Here momentum and mechanical energy is conserved.
Mass of a system is always conserved.
B. The hormone erythropoeitin increases the production of red blood cells when oxygen levels are low.
Given :
Mass of box , m = 250 kg.
Force applied , F = 285 N.
The value of the incline angle is 30°.
the coefficient of dynamic friction is .
To Find :
The speed with which the box is moving with, assuming it takes 4 seconds to reach the top of the incline.
Solution :
Net force applied in box is :
Acceleration , .
By equation of motion :
Therefore, the speed of box is 12.04 m/s.
Hence, this is the required solution.
