Answer:

Explanation:
charge of the electron = e
mass of the electron = m
Force due to electric field = F
initial velocity = 0
time taken = T
Electric field is the region around a particle which is charge where in a force is exerted on another particle which is charged.
Force on electron due to presence of uniform electric field (E):
F = e E
⇒
The longer the time taken, the lower the power output.
This is since power is calculated through
Energy transferred / time
Increasing the denominator will lead to a lower value overall
Answer:
Silk fibre is obtained from <u>silkworms</u>
whereas artificial silk is obtained by
chemical treatment of <u>wood pulp/cellulose.</u>
Explanation:
Artificial silk, or rayon, is made from cellulose, obtained from cotton or wood pulp.
So any one of them in 2nd blank is correct.
Answer:
Argon, Lithium and Potassium
Explanation:
Answer:
h= 46.66 m
Explanation:
Given that
Initial speed of the car ,u = 110 km/h
We know that
1 km/h= 0.277 m/s
u= 30.55 m/s
lets height gain by car is h.
The final speed of the car will be zero at height h.
v²=u²- 2 g h
v= 0 m/s
0²=30.55²- 2 x 10 x h ( g = 10 m/s²)
h= 46.66 m
