Answer:
1.44
Explanation:
0.1mm x 365 = 3.65mm
3.65mm into inches is 1.44
The correct answers are as follows:
<span>A region of a thinly spread gas and dust is a interstellar medium.
Inside a nebula are regions where gravity pulls togetherness gas and dust into a ball nebula.
An extreme hot ball of gas with hydrogen fusing into helium is a star.</span>
Answer:
The smallest separation distance between the speakers is 0.71 m.
Explanation:
Given that,
Two speakers, one directly behind the other, are each generating a 240-Hz sound wave, f = 240 Hz
Let the speed of sound is 343 m/s in air. The speed of sound is given by the formula as :
To produce destructive interference at a listener standing in front of them,
So, the smallest separation distance between the speakers is 0.71 m. Hence, this is the required solution.
Accel;eration due to gravity= 9.8m/s^2. Initial velocity = 0(given). Time=4. Applying kinematic equation v=u+at, v= 0 + 9.8x4 = 39.2. Therefore speed of the ball after t=4 is 39.2
This is false, materials that are poor conductors must be good insulators.
