The moon revolves around earth at a fairly constant speed.Is the moon accelerating

1 answer:

7 0

<span>If the moon changes direction, it's because it is orbiting around the earth, and the moon keeps a constant speed. And when the moon turns, it accelerates due to velocity. So yes, the moon accelerates. </span>

The primary coil of a transformer has N1 = 275 turns, and its secondary coil has N2 = 2,200 turns. If the input voltage across t

DedPeter [7]

Answer:

Secondary voltage of transformer is 905.23 volt

Explanation:

It is given number of turns in primary of transformer $N_1=275$

Number of turns in secondary $N_2=2200$

Input voltage equation of the transformer

$\Delta v=160sin\omega t$

Here $v_{max}=160volt$

$v_{rms}=\frac{160}{\sqrt{2}}=113.15volt$

For transformer we know that

$\frac{V_1}{V_2}=\frac{N_1}{N_2}$

$\frac{113.15}{V_2}=\frac{275}{2200}$

$V_2=905.23Volt$

Therefore secondary voltage of transformer is 905.23 volt

Suppose the coefficient of static friction between a quarter and the back wall of a rocket car is 0.330. At what minimum rate wo

Helga [31]

Answer: $3.23 m/s^2$

Explanation:

Given

$\mu_s =0.330$

Frictional Force is balanced by force due to car acceleration

Frictional force $F_s$

$F_s=ma_{min}$

$\mu_sN=ma_{min}$

$\mu_s\cdot mg=ma_{min}$

$a_{min}=\mu_s \cdot g=0.330\times 9.8=3.23 m/s^2$

The image produced by a convex mirror is always closer to the mirror than it would be in a plane mirror for the same object dist

rosijanka [135]

Answer:

True

Explanation:

The image produced a convex mirror is always virtual irrespective of location. The size of the image is always smaller than the object. In a plane mirror the distance of the object and the distance of the image is same. But in a convex the image distance is always less than the object distance.

So, this statement is true.
