Which device used in the Hubble telescope was later adapted for commercial use?

1 answer:

4 0

The answer is CCD. The CCD, or the charge-coupled device was used in the Hubble Space telescope and was later adapted for commercial use. CCD is a light-sensitive circuit used for storing and displaying data such as images. This is also used in digital cameras today.

If an object with 1000 lb of weight is to be raised vertically from ground level to 5 ft in two seconds, how much power is requi

tino4ka555 [31]

Answer:

The power required = 3390.9 W

Explanation:

Power: This can be defined as the time rate of doing work. The S.I unit of power is Joules.

Mathematically it can be expressed as,

P = Work/time or

P =W×V...................... Equation 1

Where P = power, w = weight, V = velocity.

Also

V = d/t ..................... Equation 2

Where d = distance, t = time.

Conversion: d = 5ft

If 1 foot = 0.3048 meters

Then, 5 ft = 5×0.3048 meters = 1.524 m.

W = 1000 lb

If 1 lb = 4.45 N,

Then 1000 lb = 1000× 4.45 N = 4450 N.

Given: d = 1.524 m, t = 2 s.

Substituting these values into equation 2

V = 1.524/2

V = 0.762 m/s.

Also substituting into equation 1

P = 4450×0.762

P = 3390.9 W.

Thus the power required = 3390.9 W

A rocket is launched with a velocity of 30 m/s at 40° to the horizontal. How far will it travel horizontally? 0 3.01 m 0 90.54 m

Lapatulllka [165]

Answer:

The horizontal distance traveled by the rocket is 90.46 m

Explanation:

Given;

initial velocity of the rocket, u = 30 m/s

angle of projection, θ = 40°

the horizontal distance traveled by the rocket = ?

The horizontal distance traveled by the rocket is given by the range of the projectile.

The range of the projectile is given as;

$R = \frac{u^2Sin(2\theta)}{g}\\\\R = \frac{(30)^2sin(80^0)}{9.8}\\\\R = 90.46 \ m$

Therefore, the horizontal distance traveled by the rocket is 90.46 m

The closest answer in the given options is 90.54 m
