Answer:
a)θ=74.03° (N-E)
b)t=1.56 hr
Explanation:
Given that
Plane speed = 200 km/h
Wind speed = 55 km/h
Now from diagram
V is the resultant velocity of plane
V=192.28 km/h towards north
From triangle ABC
θ=74.03°
Given that
d=300 km
We know that
d = V x t
300 = 192.28 x t
t=1.56 hr
Answer:
The speed of the wave remains the same
Explanation:
Since the speed of the wave v = √(T/μ) where T is the tension in the string and μ is the linear density of the string.
We observed that the speed, v is independent of the frequency of the wave in the string. So, increasing the frequency of the wave has no effect on the speed of the wave in the string, since the speed of the wave in the string is only dependent on the properties of the string.
<u>So, If you increase the frequency of oscillations, the speed of the wave remains the same.</u>
Answer:
I think it is C
Explanation:
If the temperature of a gas increases, the gas particles have a higher average speed as they gain kinetic energy. They collide more frequently with the walls of the container, which produces a bigger pressure.
According to first parity rule in a double stranded DNA %A=%T and %G=%C
