The correct answer is c because B) is a vector which includes both velocity and direction
The answer is B. The farmers will need to know what will happen as a result, to determine if it is worth releasing the insect.
<span>Velocity of Electron V1 = 1.50 Ă—10^6 m/s
Velocity of Electron V2 = 9.00 Ă— 10^6 m/s
We know the mass of electron m = 9.11 x 10^-31
Charge of the electron q = 1.60 x 10^-19
Calculating the potential energy at the two stages,
K1 = 0.5 x m V1^2 = 0.5 x 9.11 x 10^-31 x (1.50 Ă—10^6)^2 = 10.24 x 10^-19
K2 = 0.5 x m V2^2 = 0.5 x 9.11 x 10^-31 x (9.00 Ă—10^6)^2 = 368.95 x 10^-19
Change in Potential energy delta K= K2 - K1 = 358.71 x 10^-19
As we know for total energy conservation total change in energy is 0
so q x delta V + delta K = 0
delta V = - delta K / q = 358.71 x 10^-19 / 1.60 x 10^-19 = 224.19V
Potential difference for the electron to pass = 224.19V</span>
Answer:
The results of intergroup conflict are largely negative in that such a struggle lowers the morale and weakens the solidarity of the group. Conflict causes social disorder, chaos and confusion. War as a form of conflict may destroy the lives and properties of countless individuals.
The length of the pendulum is 3.3 m.
The given parameters:
- Mass, m = 1.5 kg
- Angle, θ = 35⁰
- Speed, v = 3.4 m/s
<h3>What is principle of conservation of energy?</h3>
- The principle of conservation of energy states that, the total energy of a system is always conserved.
P.E = K.E
mgh = ¹/₂mv²
gh = ¹/₂v²
g(L - Lcosθ) = ¹/₂v²
gL(1 - cosθ) = ¹/₂v²
Thus, the length of the pendulum is 3.3 m.
