You can solve this using the equation k=mv^2. k is the kinetic energy, m is the mass, and is the velocity. k=30(3.4)^2, so the answer is 346.8 J.
Can you write out the question please? :) Sorry, i don't see it on the paper
Answer:
angular speed ω = 2PI / T rad/sec
ω^2*r = M*G/r^2
r = ³√ M*G/ω^2 = ³√6.42*10^23*6.67*10^-11*88640^2/39.5 = 2.04*10^7 m

Complete Question is attached below
Answer:

Explanation:
From the question we are told that:
Side length s=1.13m
Left field strength 
Right field strength 
Front field strength 
Back field strength 
Top field strength 
Bottom field strength 
Generally, the equation for Charge flux is mathematically given by

Where
Theta for Right,Left,Front and Back are at an angle 90

Therefore
with respect to Right,Left,Front and Back
Generally, the equation for Charge Flux is mathematically also given by
Where

Therefore



Giving



Answer:
a. 2.6*10^{-5}T
b. north to south
Explanation:
In this case you have to take into account the expression for the magnetic field generated by a current

where mu0 is the magnetic permeability of vacuum, I is the current and r is the distance to the conductor in which you want to measure the field.
A) By replacing we have

B) The direction is obtained by using the right hand rule. In this case, the current is from west to east. Then the direction is from north to south
Hope this helps!!
