First you see the difference in mass numbers 238-234 = 4
Its is an alpha particle as it decreases the mass no by 4 .
at any angle between -90 and 90 degrees. In the diffused reflection ,the surface is rough and the direction of light in not the same as the incident light. It can be reflected at any angle
Answer:
Explanation:
maximum energy of capacitor
E = 1/2 C V ²
C is capacitance of capacitor and V is potential difference
given V = 88 V
E = 2002 x 10⁻⁶ J
Putting the values
2002 x 10⁻⁶ = 1/2 x C x 88²
C = .517 x 10⁻⁶ F .
In the second case
Energy E = 125 x 10⁻⁶ J .
C = .517 x 10⁻⁶
V = ?
E = 1/2 C V ²
125 x 10⁻⁶ = 1/2 x .517 x 10⁻⁶ x V²
V² = 483.55
V = 21.98 V .

Answer:
Explanation:
mass of astronaut, M = 66.5 kg
mass of tool, m = 2.3 kg
velocity of tool, v = 3.10 m/s
Let the velocity of astronaut is V.
(A) According to the conservation of moemntum
Momentum of astronaut = Momentum of tool
M x V = m x v
66.5 x V = 2.3 x 3.10
V = 0.107 m/s
(B) The direction of motion of astronaut is opposite to the direction of motion of tool.
