Answer:
The ozone layer is present in the stratosphere.
Answer:
<h3>The answer is 20 N</h3>
Explanation:
The force acting on an object can be found by using the formula
<h3>force = mass × acceleration</h3>
From the question
mass = 1000 g = 1 kg
acceleration = 20 m/s²
We have
force = 20 × 1
We have the final answer as
<h3>20 N</h3>

Answer:Metaloids have properties of both metals and non-metals.
Explanation:
Answer:
Explanation:
Let the mass of bullet is m, initial velocity of bullet is vi and c be the specific heat of the bullet.
Kinetic energy, K = 1/2 mvi^2
According to the question, 50% of the kinetic energy is equal to the heat energy absorbed by the bullet.
50% of K = mass of bullet x specific heat x rise in temperature
1/4 mvi^2 = m x c x ΔT
Answer:
<u>Speed = 1.2 m/s</u>
Explanation:
<em>Convert 20 min into seconds</em>
<em>1min= 60sec</em>
20min = 20*60 sec
<em>20 min= 1200sec</em>
Time = 1200 sec
Distance = 1000m
Speed =
Speed =
<u>Speed = 1.2 m/s</u>
<u></u>
