<span>Moment = Force × Perpendicular distance from the pivot</span>
Viefleur [7K]3 years ago

We define the turning effect with the equation: Moment = Force × Perpendicular distance from the pivot. Since force is measured in newtons (N) and distances in metres (m) the unit for a moment is the newton-metre (Nm). Moments can act in two ways: clockwise or anticlockwise.

Two rocks, a and b, are thrown horizontally from the top of a cliff. rock a has an initial speed of 10 meters per second and roc
Arte-miy333 [17]

Both rocks hit the ground at the same time and at the same distance from the base of the cliff. Option A is correct.

<h3>What is speed ?</h3>

Speed is defined as the rate of change of the distance or the height attained. it is a time-based quantity. it is denoted by u for the initial speed while u for the final speed. its SI unit is m/sec.

If the  resistance is ignored, things falling near the Earth's surface have the same estimated acceleration due to gravity of 9.8 meters per second.

As a result, the objects' acceleration is the same, and their velocity is growing at a consistent pace.

So that both rocks hit the ground at the same time and at the same distance from the base of the cliff.

Hence, option A is correct.

Find the total electric charge of 1.7 kg of electrons. me=9.11×10−31kg, e=1.60×10−19C.
Gelneren [198K]

Answer:

2.99\cdot 10^{11}C

Explanation:

The mass of one electron is

m_e = 9.11\cdot 10^{-31}kg

So the number of electrons contained in M=1.7 kg of mass is

N=\frac{M}{m_e}=\frac{1.7 kg}{9.11\cdot 10^{-31}kg}=1.87\cdot 10^{30}

The charge of one electron is

e=1.60\cdot 10^{-19} C

So, the total charge of these electrons is equal to the charge of one electron times the number of electrons:

Q=Ne=(1.87\cdot 10^{30})(1.6\cdot 10^{-19}C)=2.99\cdot 10^{11}C
