Answer:
0.015 m/s2
Explanation:
Using Newtons 2nd law.
F = ma where F = Force applied, m = mass of the object and a = acceleration acquired.
So substitute the values in SI units.
m = kg
Therefore F = 0.003×5 = 0.015 m/s2
Vapor is usually made with water and it would be made with gas.
Answer:
C
Explanation:
Angular momentum is the product of moment of inertia and angular velocity.
L = I × ω
Since the planet follows a stable circular orbit, I and ω are constant and non-zero. Therefore, the angular momentum is constant and non-zero.
Answer:
The water will rise to a height, H = 10.20 m
Given:
Atmospheric Pressure, P =
density of water,
Solution:
The water in the tube will rise to the point where the weight is balanced by the force as a result of the atmospheric pressure.
Therefore,
Pressure, P =
where
g = acceleration due to gravity = 9.8 m/s
H = height of water in the tube
Now,
Putting the values in the above formula:
H = 10.20 m
Answer:
deflected toward bottom of the screen
Explanation:
When entering the region with magnetic field, a magnetic force is exerted on the proton. This force is perpendicular to both the direction of the magnetic field and the direction of the velocity of the proton.
The direction of the force can be determined by using the right-hand rule. We have:
- Index finger: direction of the velocity of the proton --> to the right
- Middle finger: direction of the magnetic field --> into the screen
- Thumb: direction of the magnetic force --> toward bottom of the screen
So, the correct answer is
deflected toward bottom of the screen
