Answer:
changes electrical energy into mechanical energy
<u>Answer:</u>
Lead
<u>Explanation:</u>
To get the density of the material, the formula would be:
mass divided by volume which is given by .
Here in this problem, we are given a mass of which occupies a volume of .
So plugging the data in the above formula to find the density:
Density =
From the table, we can see that the material is Lead which has a density of 11.3c/cm^3.
1935.5 N is the "net force" acting on a car.
<u>Explanation</u>:
Given that,
Mass of the car is 790 kg.
Velocity of the car is 7 m/s. (v)
It turned around with 20 m. (r)
We know that, Net force = m × a
Now, Net force = m × a
Net force = 790 × 2.45
Net force = 1935.5 N
Answer:
Explanation:add them then divide them by 100 I think
Answer:
It has very high density, so a small bulb of a thermometer can contain much mercury. Mercury remains liquid state over a quite wide range of temperature because it freezes at 39°C and boils at 357°C.
