Answer:
A snorricam
Explanation:
The apparatus used here is a snorricam. A snorricam can be described to be a camera device which is used during the making of films. The snorricam is rigged to the actor. It faces him or her directly in such a way that as they walk, they would not appear to make any movements but the things around them would. It is also called the bodymount camera.
B. The Earth radiates an amount of energy into space equal to the amount it receives.
Part of the solar energy is reflected by the Earth into space, this is known as albedo. The other part of the energy radiated by the Earth in the form of infrared radiation, is absorbed by the greenhouse gases, which cause most of this infrared radiation to be emitted into space. Therefore, the net flow of energy is zero.
Answer:
0.168°C
Explanation:
The frictional force between the palms enables rubbing and initiates the heat deposed.
The energy generated per rub is;
The force × distance
Hence we have; 71.3 N×0.0750m
Hence for 11 rubs we have; 11× 71.3 N×0.0750m= 58.82J
Now this heat acquired by the tissue is the same as mass of tissue × specific heat capacity of tissue × temperature rise;
Expressed mathematically as;
58.82=0.100 kg×3500 J/(kg · °C)×∆T
∆T= 58.82/ 0.100 ×3500 =0.168°C
Answer:
9,000 N.
Explanation:
Workdone can be defined as the ability to do work. It is also the product of the force and the distance it is being moved.
Mathematically,
W = F * d
= 180,000/2
= 90,000 N.
Weight of the 10 cars = 90,000 N.
Weight of a car = 90000/10
= 9,000N.
