Answer:
The tension in the string is 16.24 N
Explanation:
Given;
mass of the sphere, m = 1.55 kg
initial velocity of the sphere, u = 2.81 m/s
final velocity of the sphere, v = 4.60 m/s
duration of change in the velocity, Δt = 2.64 s
The tension of the string is calculated as follows;
T = 1.55(0.678 + 9.8)
T = 1.55(10.478)
T = 16.24 N
Therefore, the tension in the string is 16.24 N
Answer:
The waves will turn slightly to the <em><u>left .</u></em>
Explanation :
The waves will turn slightly to the left, because the left side of each wave front hits the boundary first and slows down, moving more slowly than the right side until the right side of the wave front reaches the boundary. THis causes the wave to veer slightly to the left.
Basically the speed of water depends upon depth of the river or the ocean.
the formula is as follows :
v = √gxd
v = √d (g is the gravitational acceleration)
As the water waves are more at the deeper end then the shallow end, so during its course to the shallower end, they are slightly deviated toward the normal., hence it will move slightly to the left.
A star with no measurable parallax is very close to Earth. The statement is FALSE because Parallax angles of less than 0.01 arcsec are too difficult to measure from Earth because of the effects of the Earth's atmosphere, <span>only the </span>closer<span> ones have a </span>parallax<span> that is large enough to be measured, a</span>nd the diameter of the Earth's orbit is small compared to the distance to all but the nearest stars.
<u>Answer;</u>
<em>The moving car transfers kinetic energy to the parked car. </em>
<u>Explanation;</u>
- Energy is the ability of work to be done. It is measured in joules. The energy in an object depends on whether an object is in motion or at rest.
- Kinetic energy is the energy possessed by a body in motion. Calculated by 1/2mv², where m is the mass of the body and v is the velocity of the body in motion. Therefore, the moving car possess kinetic energy.
- When a body is at rest it posses potential energy. Thus, the parked car possessed kinetic energy which changed when it was hit by the moving car as the kinetic energy of the moving car was transferred to the parked car.
