Wind and water is the answer
Hope this helps!
Answer:
a.
Explanation:
Use accleration formula,
The initial velocity and final velocity is at zero. and t=10
So we got
so
a is the answer
Answer:
The correct answer is D
shock waves
Explanation:
When a body approaches the speed of sound in the media, the waves it emits are getting closer and closer to each other, the envelope (sum) results in a kind of cylindrical cone that is similar to that formed in a supersonic process
The correct answer is D
When the speed of sound is exceeded, the body goes faster than the wave, so the so-called shock waves are formed.
They carry a lot of energy
The strong nuclear force is responsible for holding nuclei together
Answer:
1.97 m/s.
Explanation:
From the question,
Using the law of conservation of energy,
The energy stored in the charged plate = Kinetic energy of the mass
1/2(qV) = 1/2mv².......................... Equation 1
Where q = charge, V = voltage, m = mass, v = velocity.
make v the subject of the equation
v = √(qV/m)......................... Equation 2
Given: q = 6.5×10⁻⁶ C, V = 12000 Volts, m = 0.02 kg
Substitute these values into equation 2
v = √(6.5×10⁻⁶×12000 /0.02)
v = √3.9
v = 1.97 m/s.
