4 0

Answer:

S = V0 t + 1/2 g t^2

3000 m = 1/2 * 9.8 * t^2       initial speed is zero

t = (6000 / 9.8) ^1/2 = 24.7 sec

The function of a capacitor in an electric circuit is to?
Tema [17]

Well let's see:

A). No.  A capacitor doesn't measure anything.

B). No.  The power delivered to the circuit is determined by
              the battery or power supply and all the things in
              the circuit that dissipate energy.  A capacitor doesn't
              do any of these things.

C). No.  If any current actually flows between its plates,
             the capacitor is shot and can't do its job, and
             must be replaced.

D). Yes. A capacitor stores charges on its plates, and
              electrical energy in the field between its plates.

How do u calculate momentum
Helga [31]

Answer:

Explanation:

To calculate the momentum of a moving object multiply the mass of the object times its velocity. The symbol for momentum is a small p. So, the momentum of the object is calculated to be 8.0 kg-m/s. Note the unit for momentum.

A lever has a 36cm input arm and a 6cm output arm. find MA.
Nady [450]

6

Explanation:

The mechanical advantage is a factor that measures how input force increases using a machine.

A lever is a simple machine with the fulcrum at the center.

To calculate the mechanical advantage M.A of levers we use the expression below;

M. A = \frac{F_{b} }{F_{a} } = \frac{a}{b}

F_{a} = input force

F_{b} = output force

a is the distance of the input force from the fulcrum

b is the distance of the output force from the fulcrum

Given

a = 36cm

b = 6cm

M.A = \frac{36cm}{6cm} = 6

a girl swims along the length of 80m in swimming pool and comes back in 1.5sec. find her distance and displacement​
guapka [62]

the distance is the first 80m+the second 80m she came back. So the distance is 160m. but the displacement is 0, because she came back by the direction she went.
