C 5 and 8 no
D 6 and 6 YES
Answer:The main formula is v² = u² + 2as
Explanation:
S=½(u +v)t
t = v+u/a
S=½(v-u)(v+u/a)
S=½v²+uv-uv-u²/a
2as=v²-u²
Answer:
5.3×10⁴ m/s
Explanation:
From the question,
Momentum = mass× velocity
M = mV................ Equation 1
Where M = momentum of the airplane, m = mass of the airplane, V = Velocity of the airplane
make V the subject of the equation
V = M/m.................. Equation 2
Given: M = 1.6×10⁹ Kg.m/s, m = 3.0×10⁴ kg
Substitute these values into equation 2
V = 1.6×10⁹/3.0×10⁴
V = 5.3×10⁴ m/s
here since string is attached with a mass of 2 kg
so here tension force in the rope is given as
here we will have
now we will have speed of wave given as
here we will have
now we know that frequency is given as
F = 100 Hz
now wavelength is given as
so wavelength will be 0.16 m
