Answer:
The velocity when the ball hits the ground is obtained using v2. 2 = v1. 2 + 2 g Dy with v1=0 and Dy=h. Thus solving for v2 yields 17.1 m/s v2 = 2 g h =.

The first step to take is to check the anemometer to determine the intensity of the wind blowing in the open ocean. The measurement is in terms of knots or nautical miles. Next, we use a Beaufort scale to check what range the knots falls in. Using the scale, we can see what is the height of the wave. The Beaufort scale is used in open oceans only
Answer:
The magnetic force will be 0.256 N in +y direction.
Explanation:
It is given that, a wire along the z axis carries a current of 6.4 A in the z direction. Length of the wire is 8 cm. It is placed in uniform magnetic field with magnitude 0.50 T in the x direction.
The magnetic force in terms of length of wire is given by :

For direction,

So, the magnetic force will be 0.256 N in +y direction.
Answer:Total atmospheric mass is 5.1480×1018 kg (1.135×1019 lb), about 2.5% less than would be inferred from the average sea level pressure and Earth's area of 51007.2 megahectares, this portion being displaced by Earth's mountainous terrain.
Explanation:
The magnetic force acting on a charged particle when placed in a magnetic field is given by :


is the angle between v and B.
If means that if the angle between v and B is 0 degrees or both are acting in same direction, then magnetic force is equal to 0.
Here, a charge is moving in a magnetic field that points to the left. Hence, for a charge particle that experiences no magnetic force, the charge must move in the left direction such that they move parallel to each other.
