Answer: 2.5

Explanation:

The mass of bullet = 20kg

The momentum of the bullet = 10kg m/s

The kinetic energy of this bullet in Kj will be calculated as:

= p² / 2m

= 10² /(2 × 20)

= (10 × 10) /(2 × 20)

= 100/40

= 2.5

Therefore, the correct option is C.

What type of eclipse is shown? How do you know?
Sonja [21]
That is a lunar eclipse. At night, when the Earth is between the Sun and the moon, the moon would appear to be red. Just for future reference, a solar eclipse is when the Moon is between the Sun and Earth. Speaking of which, check out the solar eclipse this August!

Ellie has two wire circuits, each connected to its own 6 V battery. One circuit has a resistance of 0.80 Ω. The other circuit ca
Vikentia [17]

The second circuit with 4.5 A current has more resistance.

Explanation:

potential difference= 6 V

resistance of first circuit=0.80 Ω

for second circuit, current= i=4.5 A

using Ohm's law V= i R

6=4.5 R

R=1.33 Ω

So the second circuit has a greater resistance.
