Answer:
The magnitude of the electric field is 
Explanation:
Given that,
Time t = 2.10 s
Speed = 160 m/s
Specific charge =Ratio of charge to mass = 0.100 C/kg
We need to calculate the acceleration
Using equation of motion
Put the value into the formula
We need to calculate the magnitude of the electric field
Using formula of electric field
Put the value into the formula
The direction is upward.
Hence, The magnitude of the electric field is
True
Explanation:
In order to apply and experience the beauty of mathematics, a good comprehension of the discipline is required.
In fact, this is general to anything in life. To fully maximize any potential, one must be well groomed about what exactly that thing is.
Mathematics is a science that deals with the logic of shapes and numbers. There are different branches of this discipline with real world adoption.
The tenets of mathematics cuts across business, science, arts, e.t.c.

Answer:
What is the problem I cant help unless you have the problem.
Explanation:
Number 4 I think
the atomic mass is 11 because the mass is the sum of protons and neutrons
Answer:
Option C - 39.2 J
Explanation:
We are given that;
Mass; m = 2 kg.
Distance moved off the floor;d = 10 m.
Acceleration due to gravity;g = 9.8 m/s².
We want to find the work done.
Now, the Formula for work done is given by;
Work = Force × displacement.
In this case, it's force of gravity to lift up the boots, thus;
Formula for this force is;
Force = mass x acceleration due to gravity
Force = 2 × 9.8 = 19.2 N
∴ Work done = 19.6 × 2
Work done = 39.2 J.
Hence, the Work done to life the boot of 2 kg to a height of 2 m is 39.2 J.
