Answer:
42.11 sec
Explanation:
In first part : The truck start from the rest that is u = 0 m/sec
Acceleration is given as 
It reaches to a velocity of 22 m/sec so v=22 m/sec
Now according to first law of motion 


In second part : The truck maintain a constant speed for 22 sec
In third part : The truck takes an additional 4.4 sec for stopping
So total time in which the truck is in motion =15.71+22+4.4=42.11 sec
Answer:
In the picture.
Explanation:
I hope that it's a clear explanation.
The electric field at any point in the region between the conductors is proportional to the magnitude Q of charge on each conductor. It follows that:
"The potential difference Vab between the conductors is also proportional to Q"
If we double the magnitude of charge on each conductor, the charge density at each point doubles, the electric field at each point doubles, and the potential difference between conductors doubles; however, the ratio of charge to potential difference does not change. This ratio is called the capacitance C of the capacitor:

Given that:

and
Lastly, the capacitance is given by:
Elliptical galaxies are galaxies that are shaped like an ellipse. An ellipse is oval in shape, which means elliptical galaxies are oval in shape.
The <u>two correct statements</u> that describe elliptical galaxies are:
B. They are the most common galaxy type.
C. They typically contain very little gas and dust.
- Elliptical galaxies are galaxies where you will find little or no gas and dust. The galaxies that are numerous in number are the elliptical galaxies.
- In the elliptical galaxy, you can't find any <u>spiral component </u>in it.
Therefore, from the above explanation, we can see that <u>option B and C is the correct option.</u>

Answer:
In the air
Explanation:
light in air flows in a straight direction while in water it curves far away from the object(refraction)thus the bear in the air will catch the fish easily because in water the fish is refracted thus the bear may catch its refracted image thinking it is the fish
