Answer:
due to the inertia of motion, the fan continues to move for some time even after switching it off.
Answer:
W_net = mg + 2mgh/r
Explanation:
The forces applied in this motion of the bowling ball are both gravitational and centripetal forces.
Now, gravitational force is; F_g = mg
While centripetal force is; F_c = mv²/r
Since we want to express the net force in terms of the variables in the statement and we are not given "v", let's find an expression of v with the variables given.
Now, from Newton's equation of motion, at initial velocity of 0, v² = 2gh.
Thus;
F_c = 2mgh/r
Where;
m is ball mass
r is tube radius
h is fall height
Thus, the net force will be;
F_net = F_g + F_c
Now, Net force would be equal to the net weight that will be read on the scale.
Thus;
W_net = F_net = F_g + F_c
W_net = mg + 2mgh/r
Answer:
The color of the central maximum is white.
Explanation:
A diffraction grating in optics is generally known as an optical component that contains a periodic structure. It is commonly used to breakdown and diffract light into different beams that move in several directions. For example, if a light ray is allowed to pass through the component (i.e. diffraction grating), the central maximum will have a white color.
The bullet will strike the target placed in 324.0 m in the East in 0.45 seconds.
<u>Explanation:</u>
As we all know the epic relation between distance, speed and time; we cam easily estimate the time in which an object can reach to the destination or target.
As here in this case, we know the distance of the target and the velocity of a bullet exerted from a rifle given as follows,
Distance of the Target from the rifle edge = 324.0 m
Velocity of bullet exerted from the rifle = 720 m/s
Since we know that,
or
We can simply implement all the values in the formula and get the results i.e the time required by the bullet to hit the target. Since both the values are in S.I units measures, we don't need to change or convert any of them. Hence,
Therefore, the bullet will hit the target in 0.45 seconds.
Well the options r not well described anyways, the answer goes:
1) Foods rich in carb, sugars, proteins...
2) Lack of activity/exercise
3) Not proper use of medicines
4) Imbalanced hormone
5) Dehydration
6) Stress (in some situations)
7) High intake of unhealthy beverages (i.e, juices, alcohol & alike)
And much more
Hope this was helpful :)
