Multiply field strength (N/kg) by mass (kg) to get weight (N)

At the start, the car is carrying

4.7 kg * (9.8 N/kg) = 46.06 N

of fuel.

At the end, it is carrying

3.0 kg * (9.8 N/kg) = 29.4 N.

Assuming the car remains completely intact, its weight was reduced by

46.06 N - 29.4 N = 16.66 N.

A friend says that the reason one's hair stands out while touching a charged Van de Graaff generator is simply that the hair str
Llana [10]

Answer:

Explanation:

Yes I agree with the statement .

When a person who is perfectly insulated from the earth , touches a Van de Graaff , his body acquires charge . when the hair acquires it, it stands out due to mutual repulsion . It is to be noted here that at pointed areas on a surface , there is larger accumulation of charge. Accumulation of charge is greater at hair tops .

It is also a general observation that when a bird sits on high tension wire , his feather stands out due to the same reason.

Puck 1 (1 kg) travels with velocity 30 m/s to the right when it collides with puck 2 (1 kg) which is initially at rest. After th
Katyanochek1 [597]

Answer:

v₂ = 22.5 m/s

Explanation:

Given that

For puck 1

m₁= 1 kg

u₁= 30 m/s

For puck 2

m₂= 1 kg

u₂= 0 m/s

After collision

Puck 1 have velocity v₁=7.5 m/s

Take puck 2 will have velocity v₂

From linear momentum conservation

P₁=P₂

m₁ u₁+m₂ u₂=m₁ v₁+m₂ v₂

1 x 30 + 1 x 0 = 1 x 7.5 + 1 x v₂

30 - 7.5 =v₂

v₂ = 22.5 m/s

Doug, who runs track for his high school, was challenged to a race by his younger brother, matt. Matt started running first, and
eduard

The speed of Matt is 10 mph.

Doug runs 2 miles an hour faster than Matt, so let Matt’s speed equal x miles per hour. Then Doug’s speed equals x + 2 miles per hour. Each lap is one-quarter of a mile, so Doug runs 1.5 miles in the time it takes Matt to run 1.25 miles.

Rate of Matt is x

Rate of Dough is (x + 2)

Time taken by Matt is 1.25/x

Time taken by Dough is 1.25/(x + 2)

Distance covered by Matt is 1.25

Distance covered by Dough is 1.5

Dough and  Matt  took the same amount of time from the time Doug started, so make an equation by setting the two times in the chart equal to each other, and then solve for x:

            \frac{1.5}{(x + 2)} = \frac{1.25}{x}

              1.5x = 1.25(x + 2)

              1.5x = 1.25x + 2.5

           0.25x = 2.5

                   x = 10

So Matt ran at 10 miles per hour.

Marina86 [1]

Answer:

Seafloor spreading is a geologic process in which tectonic plates—large slabs of Earth's lithosphere—split apart from each other. ... As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense.
