Answer:
Workdone = 1.96 Nm
Explanation:
Given the following data;
Mass = 100g to kg 100/1000 = 0.1Kg
Distance = 2m
To find the workdone;
First of all, we would determine the force acting on the apple
Force = mass * acceleration due to gravity
But, acceleration due to gravity is equal to 9.8m/s²
Force = 0.1 * 9.8
Force = 0.98N
Now, we can find the workdone using the formula;
Workdone = force* distance
Substituting into the equation, we have
Workdone = 0.98 * 2
Workdone = 1.96 Nm
The only information you would need to decide if the can will float is the density of the can, which requires knowing the mass and volume. If the density of the can is less than one, the can will float. if it is greater than one, it will not float, as water's density is one.
The volume of the room is the product of its dimensions:
Now, from the equation
where d is the density, m is the mass and V is the volume, we deduce
So, multiply the density and the volume to get the mass of air in the room.

Answer:
Explanation:The four closest to the sun — Mercury, Venus, Earth and Mars — are the terrestrial planets. They have rocky surfaces enclosed by relatively shallow atmospheres.
