Answer:
1.2 amps :)
Explanation:
A heater has a resistance of 10.0 Ω. It operates on a 12.0 V. What is the current through the resistor?
Known:
Unknown:
I = V/R
= 12.0 V / 10.0 Ω
= 1.2 amps

The number of electrons strike the screen each minute when thee current in the electron beam of a typical video display terminal is 200 µa is 7.5×10¹⁶.
<h3>How to calculate electric charge?</h3>
Electric charge is equal to the product of electricity current flowing and the total time. It can be given as,
Here, I is current and t is time.
The current in the electron beam of a typical video display terminal is 200 µa for one minute. Thus, the total charge is,
The number of electron flow is the ratio of total charge to the charge of one electron. The charge on one electron is 1.6×10⁻¹⁹ C. Thus, the number of electron is,
Thus, the number of electrons strike the screen each minute when the current in the electron beam of a typical video display terminal is 200 µa is 7.5×10¹⁶.

Answer: Blake may have a decreased chance of disease.
Explanation:
Research has shown that on average, a person who engages in more physical activity will live longer than a person who does not with one reason for this being that engaging in physical activity helps reduce the risk of diseases such as; heart disease, diabetes, and many forms of cancer.
Obesity (risk factor) and high blood pressure are also reduced by engaging in physical activity.
Answer:
Explanation:
moment of inertia of reel = 1/2 mr² , m is mass and r is radius of the reel
= .5 x .7 x .0524²
= 96.1 x 10⁻⁵
If force required be F
F x .0524 - 1.88 is net torque acting on the reel
F x .0524 - 1.88 = moment of inertia x angular acceleration.
F x .0524 - 1.88 = 96.1 x 10⁻⁵ x 65.7
F x .0524 - 1.88 = .063
F x .0524 = .063 + 1.88
F = 37.08 N
