Answer:
Explanation:
Falling objects form an interesting class of motion problems. For example, we can estimate the depth of a vertical mine shaft by dropping a rock into it and listening for the rock to hit the bottom. By applying the kinematics developed so far to falling objects, we can examine some interesting situations and learn much about gravity in the process.
In order to recreate the process of energy production that takes place in the Sun, scientists use nuclear fusion.
Answer:
The acceleration of the proton is 1.403 x 10⁹ m/s²
Explanation:
Given;
speed of proton, v = 7.7 m/s
magnitude of magnetic field, B = 1.9 T
Magnetic force of moving proton is given by;
F = qvBsinθ
Centripetal force on the moving proton is given by;


where;
q is charge of the proton = 1.602 x 10⁻¹⁹ C
m is mass of proton = 1.67 x 10⁻²⁷ kg

Therefore, the acceleration of the proton is 1.403 x 10⁹ m/s²
Answer:
3.214 m
Explanation:
Here object is moving in a constant acceleration. Then we can use motion equations to find the total distance
V² = U² + 2as
0 = 1.5² + 2×-0.35 × s
s = 3.214 m
symbols has usual meanings.
