No, one more group must get the same result as the other group. This will make it more reliable and reproducible.

A physicist wants to measure the force required to push a heavy box up a ramp. What tools might the physicist use? What measurem
Flauer [41]

Answer:

Dynamometer

Explanation:

We might want to use a system that calculates weight, but we would need to change it for the task, depends entirely on the task. Let 's imagine we're taking a scale to test people's weight, and you're moving it between something that moves the box and the box that are being moved, because when we push you will see the scale calculate distance. Then force until the container continues to flow.

What causes the different season on earth
viktelen [127]

The Short Answer: Earth’s tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun’s most direct rays. So, when the North Pole tilts toward the Sun, it’s summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it’s winter in the Northern Hemisphere.

How high will a 0.345 kg rock go if thrown straight up by someone who does 111 J of work on it? Neglect air resistance.
Eddi Din [679]

To solve this problem we will apply the concepts related to energy conservation. Here we will understand that the potential energy accumulated on the object is equal to the work it has. Therefore the relationship that will allow us to calculate the height will be

W = PE

W = mgh

Here,

m = mass

g = Acceleration due to gravity

h = Height

our values are,

m = 0.345 kg

g = 9.8m/s^2

W = 111J

Replacing,

W =mgh

111 = (0.345)(9.8)h

h = 32.83m

Then the height is 32.83m.
