Answer:
The electric flux through the sphere is 
Explanation:
Given

Required
Find the electric flux
Electric flux is calculated using the following formula;
Ф = q/ε
Where ε is the electric constant permitivitty
ε 
Substitute ε
and
; The formula becomes
Ф = 
Ф = 
Ф = 
Ф = 
Ф = 
Ф = 
Ф = 
Ф = 
Hence, the electric flux through the sphere is 
Weight = Mass * gravity
= 1470* 9.8 = 14406 N ≈ 14,400 N
No, if it takes less time, the acceleration is greater.
Hope this helps!
Answer: 20.2 m/s
Explanation:
From the question above, we have the following data;
M1 = 800kg
M2 = 1200kg
V1 = 13m/s
V2 = 25m/s
U (common velocity) =?
M1V1 + M2V2 = (M1 + M2). U
(800*13) + (1200*25) = (800+1200) * U
10400 + 30000 = 2000u
40400 = 2000u
U = 40400 / 2000
U = 20.2 m/s
Answer:
Explanation:
Given
initially steam is at
and converted to
ice
Let m be the mass of steam
latent heat of fusion and vaporization for water is


Heat required to convert steam in to water at 

Heat required to lower water temperature to 



Heat required to convert
water to ice at
is





So this energy is equal to kinetic energy of bullet of mass m moving with velocity v
