Answer: A negatively charged particle that is found in atoms.
Answer:
P=F/A where F is the weight of the water and A is the area on which it is resting. The weight of the water is mg. The mass of the water is dv where d is the density and v is the volume. Finally, the volume of the water in a vessel is equal to the area of the base of the vessel times the height of the vessel. (v=Ah)
Plugging everything in we get:
P = dAhg/A
So
P=dhg
So we have shown that liquid pressure is directly proportional to height of liquid in a vessel.
The NE Patriots will. Just you wait and see. And when thay do, remember
that you saw the correct prediction right here on Brainly, posted by AL2006.
You are asked to calculate an object's velocity.
In order to do so, you must know the object's speed and the direction
in which it's moving, or you must have other information that makes it
possible for you to calculate its speed and direction.
Answer:
66.02m/s
Explanation:
the equation describing the distance covered in the horizontal direction is
but the acceleration in the horizontal path is zero, hence we have
Since the horizontal distance covered is 155m at 7.6secs, we have 
Also from the vertical path, the distance covered is expressed as
since the horizontal distance covered in 7.6secs is 195m, then we have
Hence if we divide both equation 1 and 2 we arrive at
Hence if we substitute the angle into the equation 1 we have
Hence the initial velocity is 66.02m/s
