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 
Answer:
Depth is 7.49cm
Explanation:
Given that;
The diameter of tube is (D)=4.7cm
Area of the tube is =πD^2/4
Area is 3.142*4.7*4.7/4=17.35cm2
Mass(M)=130g
Density =1g/cm^3
Recall that Density =mass /volume
Hence volume =130/1=130cm^3
Also note
Volume=area*depth
130=17.35*depth
Depth=130/17.35=7.49cm
True, the accepted modern theory of life is biological evolution.
Electric motors require electricity to move the motor parts and do work (like an electric fan).
Elecgric generators actually burn diesel fuel to spin a motor around and around and around to GENERATE, or MAKE, electricity that you can then use to power your fans and lights in your house.

Explanation:
Crust : The crust is the thinnest layer of the Earth. It has an average thickness of about 18 miles below land, and around 6 miles below the oceans. The crust is the layer that makes up the Earth's surface and it lies on top of a harder layer, called the mantle.
Mantle : The mantle is the mostly-solid bulk of Earth's interior. The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust. The mantle is about 1,802 miles thick, and makes up a whopping 84% of Earth's total volume
Outer Core : The outer core is the third layer of the Earth. It is the only liquid layer, and is mainly made up of the metals iron and nickel, as well as small amounts of other substances. The outer core is responsible for Earth's magnetic field. As Earth spins on its axis, the iron inside the liquid outer core moves around.
Inner Core : It's Almost The Size of the Moon. The Earth's inner core is surprisingly large, measuring 1,516 miles across. It's Mostly Made of Iron. It Spins Faster Than the Surface of the Earth. It Creates a Magnetic Field.
