In an uniformly accelerated motion, the velocity of the object follows the law:
where
is the initial velocity, a the acceleration and t the time.
In our problem, the robot starts from rest, so the initial speed is zero:
. The robot is in free fall, so the acceleraion is the gravitational acceleration
. therefore, after a time
, the velocity is
Answer:
2.88 × 10⁻¹⁸ C
Explanation:
The charge on a proton and electron are the same and it is = 1.6 × 10⁻¹⁹ C
The net charge electric charge of an iron atom = (number of proton × charge on a proton) + ( number of electron × charge on an electron ) = 26 (e) + 8 (-e) = 26 e - 8 e = 18 e = 18 × 1.6 × 10⁻¹⁹ C = 2.88 × 10⁻¹⁸ C
The displacement of Edward in the westerly direction is determined as 180.27 km.
<h3>Displacement of Edward</h3>
The displacement of Edward is calculated as follows;
R² = a² + b² - 2abcosθ
R² = 150² + 200² - 2(150 x 200) x cos60
R² = 32500
R = 180.27 km
Thus, the displacement of Edward in the westerly direction is determined as 180.27 km.

Explanation:
<u>Rated </u>
A t-rated switch may be used to (its/a) <u>Rated</u> current capacity current capacity when controlling an incandescent lighting load.
<h3>What is "current rating"?</h3>
- The greatest current that a fuse is rated to carry for an infinite duration without significantly degrading the fuse element is known as the current rating.
- There is also a large selection of power switching transistors that have voltage ratings well over 1000V and current ratings up to several hundred amps.
<h3>What does the term "rated current" mean?</h3>
- When an electrical device receives its rated voltage and outputs its rated power, it flows at its rated current.
- So, when a device is designed for a certain amperage, that amperage is referred to as the equipment's rated current.
<h3>What does electrical "rated" mean?</h3>
- An electrical appliance's rating reveals the voltage range at which it is intended to operate as well as the current consumption at that range.
- These numbers are typically shown on a rating plate that is fastened to the device, such as 230 volts, 3 amps.
