hello! i believe it would be A.
Answer:
The salt is dissolved by the water and heat. If the pot isn't boiling, the salt wouldn't dissolve, it would stay undissolved.
Answer:
Explanation:
We start converting to SI units,
A mile = 1609m
We know that the expression, which can relate linear acceleration and angular velocity is given by,
Where is the angular velocity
r=radius
linear acceleration,
Re-arrange for \omega,
Our acceleration is equal to the gravity force, so replacing,
A gas heated to millions of degrees would emit mostly x-rays.
The velocity of the ball at its maximum height is zero (0).
The given parameters;
- <em>initial vertical velocity of the ball, </em><em> = 18.5 m/s</em>
- <em>height of the cliff, h = 25</em>
<em />
In a projectile motion, as the object ascends upwards, its vertical velocity decreases and eventually becomes zero as the object reaches maximum height.
This <em>velocity</em> starts to increase again as the object descends downwards and finally becomes maximum before the object hits the ground.
Thus, we can conclude that the velocity of the ball at its maximum height is zero (0).
