What is the weight of a text book whose mass is 2.4 kg measured on the moon? The gravitational acceleration on the moon is approximately 1/6 that on the earth.

Answers

Answer:

2.4 kg

1 kg = 10N

2.4 kg = ?

2.4 kg = 24N

On the moon 1/6th

1/6 * 24 = 4N

therefore weight of the textbook on the moon would be 4N

Can you help me understand force=mass x accleration

Answers

Force = mass * acceleration

Here is an equation for force, used to calculate force. 

Look at it this way:-

Joules is used to measure force, while mass is measured by kg. Acceleration is measured by m/s/s (meters per second per second, or meters per second squared.)

joules = m/s/s * kg 

Which makes everything fit in just right! :D

Answer:

so your wondering how electricity goes from power plants to your home? well, here's why.The electrical charge goes through high-voltage transmission lines that stretch across the country. It reaches a substation, where the voltage is lowered so it can be sent on smaller power lines. It travels through distribution lines to your neighborhood.
Electricity goes from power plants to our homes through a step-down transformer. This helps the voltage to be lowered because electricity has to have high amounts of voltage to travel. So once it’s been lowered, electricity gets transferred to smaller wires that connect to our outlets.

Name the apparatus used to measure friction force? PLEASE HELP AS SOON AS POSSIBLE

Answers

There is no apparatus for it. It is either use something like ruler and table and rub together or rub our hands, and friction force will be showed.
