Answer:

24kgm/s

Explanation:

Given parameters:

Force = 80N

Mass of object = 6kg

Initial velocity = 4m/s

Final velocity = 8m/s

Solution:

Impulse = ?

Solution:

The impulse on a body is its change in momentum.

Impulse = m (v - u )

m is the mass

v is the final velocity

u is the initial velocity

Now insert the parameters and solve;

Impulse = 6 (8 - 4) = 24kgm/s

If you connect two identical storage batteries together in series (" " to "-"), and place them in a circuit, the combination wil

Lelu [443]

Answer:

4 (D): twice the voltage, and the same current will flow through each.

Explanation:

When we have batteries in series in a circuit, the equivalent voltage will be the sum of their voltages, and the current flowing through then will be the same.

These batteries are identical, so they have the same voltage, therefore when they are put in series, the equivalent voltage will be twice the voltage of one battery.

So the correct option is 4 (D): twice the voltage, and the same current will flow through each.

The near point of an eye is 48.5 cm. A corrective lens is to be used to allow this eye to focus clearly on objects at the distan

Masteriza [31]

Answer:

The focal length of the lens should be -51.5 cm (a concave lens).

Explanation:

The purpose of the lens is to make objects at 48.5 cm appear at the healthy near point. The healthy near point is 25.0 cm.

We use the lens formula

$\dfrac{1}{f} = \dfrac{1}{u} + \dfrac{1}{v}$
