How do you find weight =mass×gravitational acceleration
Answers
That's a formula that shows the relationship between three quantities ... weight, mass, and acceleration. If you know any two of them, then you can use this formula to find the one you don't know.
Examples:
==> I have a rock with 2 kilograms of mass. The gravitational acceleration on Earth is 9.8 m/s² . How much does my rock weigh on Earth ?
Weight = (mass) x (grav acceleration) = (2 kg) x (9.8 m/s²) = 19.6 newtons (about 4.41 pounds)
==> My brother weighs 770 newtons (about 173 pounds) on Earth. What is his mass ?
Weight = (mass) x (grav acceleration)
770 newtons = (mass) x (9.8 m/s²) Divide each side by 9.8 m/s²: 770 newtons / 9.8 m/s² = mass
78.57 kilograms = mass
==> When I went to the Moon, I took along my 2-kilogram rock. I weighed my rock on the Moon. It weighs 3.25 newtons (about 0.73 pound) there. What is the gravitational acceleration on the Moon ?
Weight = (mass) x (grav acceleration)
3.25 newtons = (2 kg) x (acceleration)
Divide each side by 2 kilograms: (3.25 newtons)/(2 kg) = acceleration
1.63 m/s² = grav acceleration on the Moon
By plugging in the variables duh. Hahhha so look at your problem and plug in the numbers to what they are.
Why is it important for scientists to be curious?
Answers
it is important for scientists to be curious because they will never find out the answer to their curiosity unless they well find out
It's important for scientists to be curious because everyday we live in a specticul world. and as soon as we learn how to talk our language starts to get more and more advance. But then we start to ask question's that lead up to our curiosity. this is very important because we can make a difference in life. we can uncover new mysteries that appear based on a theory.
I hopee this helped you
An 100W light bulb is on 6 hours work out the energy (kWh) used and the cost of it (1kWh = £0.1359) with working out please
Answers
1,000 W = 1 kW 100 W = 0.1 kW
(0.1 kW) x (6 h) = 0.6 kWh <=== energy
(0.6 kWh) x (£0.1359/kWh) = £0.0815 <=== cost of it

Explain why the gravitational acceleration of any object near earth is the same matter what was the mass of the object
Answers
It takes greater force to accelerate an object that has more mass. But the gravitational force between the Earth and an object is greater when the object hass more mass. It works out just right to make any object with any mass accelerate at the same rate.
