Answer:
It's constant everywhere in its trajectory.
Explanation:
the projectile was launched with an initial velocity, the only acceleration that is affecting the projectile's velocity is gravity.
The acceleration of gravity is practically equal everywhere on earth, so during its trajectory, we have to take into consideration only the acceleration because of gravity.
This is only correct because the projectile was launched with an initial velocity and it's not accelerating from rest and then falls.
Answer:
Explanation:
As we know by radioactivity law
so here we will have
now we will have
now we also know that
Answer:
maybeeeeeeeee launcherrr im not sureee hehe
Work needed = 23,520 J
<h3>
Further explanation
</h3>
Given
height = 12 m
mass = 200 kg
Required
work needed by the crane
Solution
Work is the transfer of energy caused by the force acting on a moving object
Work is the product of force with the displacement of objects.
Can be formulated
W = F x d
W = Work, J, Nm
F = Force, N
d = distance, m
F = m x g
Input the value :
W = mgd
W = 200 kg x 9.8 m/s²x12 m
W = 23520 J
The atmosphere is made up of layers which vary in temperature and other characteristics.
<h3>Layers of the atmosphere</h3>
The atmosphere is divided into several layers. The atmosphere refers to the thin layer of air that lies above the earth crust. The following describes the layers of the atmosphere.
- The troposphere refers to the layer where weather changes largely occur and clouds form.
- The stratosphere has an average temperature of about 270 K (−3°C or 26.6°F). The ozone layer is found in the stratosphere.
- The temperature in he mesosphere is about − 85°C (− 120°F).
- The thermosphere has a temperature of 200° C (360° F). The ionosphere is found within the thermosphere.
