Write down any four points that should be considered during household wiring

2 answers:

8 0

1. Safety equipment is available
2. Person attempting the task has some general knowledge about wiring
3. Not All Cable is Color-Coded
Cable-sheath color coding started in 2001 and is still voluntary. If you have older wiring, don’t assume it complies with the current color coding. However, most manufacturers now follow the standard color code.
4. Stranded wire is more flexible than solid. If you’re pulling wire through conduit, stranded wire makes it easier to get around corners and bends in the conduit. However, if the situation requires pushing wires through conduit, you’ll want to use solid wire.

What is the acceleration that earth experiences due to your gravitational pull?

djverab [1.8K]

Answer:

The acceleration that earth experiences due to gravitational pull is = 9.81 $\frac{m}{s^{2} }$ .

Explanation:

The acceleration that earth experiences due to gravitational pull is called the acceleration due to gravity. its value is 9.81 and its unit is $\frac{m}{s^{2} }$ .

When the object move upwards than in that case the earth gravitational force pulls down the body.

The formula of force due to gravity on the body is given as

F = mg

where g = acceleration due to gravity.

Due to this acceleration the body falls upon the surface of the earth.

A 2-kg toy car accelerates from 5 to 10 m/s.

andre [41]

<h3><u>Full Question:</u></h3>

A 2-kg toy car accelerates from 5 to 10 m/s in 2 seconds. Find the applied force.

<h2><u>Answer:</u></h2>

Force applied is $5\frac {kgm} {s^2}$ .

<h3><u>Explanation:</u></h3>

Force is defined as something which changes or tends to change the velocity of a body. And acceleration is defined as the rate of change of velocity of a body per time. Both of them are vector quantities.

The initial velocity of the body = 5 m/s.

The final velocity of the body = 10 m/s.

So the change in velocity = 10 - 5 m/s = 5m/s.

Time period = 2 seconds.

So acceleration = $\frac52 m/s^2$ = $2.5 m/s^2$

The force is defined as the product of mass and acceleration of the body.

Mass of body = 2 kg.

So, force applied = $2 \times 2.5 kgm/s^2$ . = $5kgm/s^2$ .

A 10.0-kg animal is running at a rate of 3.0 m/s. What is the kinetic energy of the animal?

Ilya [14]

Kinetic energy is calculated by using formula:

Ek = 1/2*m*v^2

Now we replace values of mass and speed in this formula.

Ek = 1/2*10*3^2 = 45.0J

When you have a formula and all variable values are given in the text of question just replace variable values in equation and find the final value.
