Answer:
The value of acceleration due to gravity is independent of mass of the body.
Explanation:
Let us consider the mass of the object as m and mass of earth as M
Therefore, force between the object and earth would be given by: F = GMm/d²
This force is equal to the weight of the object, i.e. mg
Thus;
mg = GMm/d²
g = GM/d²
Therefore, the value of acceleration due to gravity is independent of mass of the body.
Answer:
t = 1
Explanation:
you dont know the value of the variable
Answer:
the speed of electron is 4.42 x 10⁶ m/s
the speed of proton is 2406.7 m/s
Explanation:
Given;
electric field strength, E = 478 N/C
charge of the particles, Q = 1.6 x 10⁻¹⁹ C
mass of proton, Mp = 1.673 x 10⁻²⁷ kg
mass of electron Me = 9.11 x 10⁻³¹ kg
time of motion, t = 54.2 ns = 54.2 x 10⁻⁹ s
The magnitude of charge experienced by the particles is calculated as;
F = EQ
F = 478 x 1.6 x 10⁻¹⁹
F = 7.648 x 10⁻¹⁷ N
The speed of the particles is calculated as;
The horizontal distance XQ traveled by the bomb is 250 m.
<h3>
Distance X Q</h3>
Let the XQ be the horizontal distance traveled by the bomb.
<h3>Time for the bomb to drop from 100 m</h3>
h = vt + ¹/₂gt
Let the vertical velocity = 0
h = 0 + ¹/₂gt²
h = ¹/₂gt²
2h = gt²
t² = 2h/g
t = √(2h/g)
t = √(2 x 100 / 9.8)
t = 4.5 s
<h3>Horizontal distance traveled by the bomb</h3>
XQ = vx(t)
where;
vx is horizontal speed, = 200 km/hr = 55.56 m/s
XQ = 55.56 x 4.5
XQ = 250 m
Thus, the horizontal distance XQ traveled by the bomb is 250 m.
