We don't have much to go on.
The dimensions of D depend on the dimensions of N, n, and x, and we don't know what any of those stand for.
It might help if we had ever heard of 'diffastion', but we're striking out there too.
Explanation: Each state of matter behaves differently and the particles in each state behave differently. This diagram compares the particles in a gas, a liquid and a solid.
Answer:
The gravitational acceleration is same for all objects.
a = b = c = d
Explanation:
Acceleration due to gravity or gravitational acceleration is the force exerted by Earth on unit mass of an object.
Acceleration due to gravity doesn't depend on the height of the object when the height is object is near to the surface of the Earth. Only when the height is comparable to the radius of the Earth, the value of gravitational acceleration changes.
But for the objects here, the gravitational acceleration is independent of the mass or height of the objects and has a constant value of 9.8 m/s².
Therefore, the gravitational acceleration of all the objects is same.
If 'a', 'b', 'c', and 'd' represent gravitational accelerations of objects 'a', 'b', 'c', and 'd' respectively, then a = b = c = d.
Answer:
a particular kind of matter with uniform properties.
Explanation:
Answer:
on the planet
on earth
Explanation:
Given:
- initial velocity of the tool before pushing,
- force applied on the tool,
- displacement of the tool,
- time taken for the displacement,
- height of releasing the tool,
- time taken by the tool to fall on the ground,
<u>Now using the equation of motion:</u>
where:
a = acceleration of the object
Now the mass of the tool:
<u>Using the equation of motion when the tool is dropped:</u>
here:
g = acceleration due to gravity on the planet
Weight of the tool in the planet:
Weight of the tool on the earth:
