Answer:

The two factors that affect the type of Shadows formed are stated below ::

The distance between the source of land and the object.
The angel where the ray of light falls on the object.

Answer:

The distance of the source of light from the object.

The angle at which the light rays fall on the object.

The size of the opaque object.

The size of the shadow depends on the distance of the source of light and on the angle at which the light rays fall on the object.

If the source of light is closer to the object, a larger shadow is formed than when the source of light is far from the object.

Explanation:

picture is in the top ️️️⬆️⬆️⬆️⬆️⬆️

It can be observed from the above figure that as the angle of light incident on the object changed the length of the shadow changed.

What is the centripetal force acting on a 1.5 kg mass moving in a circular path with a centripetal

zloy xaker [14]

The centripetal force acting on a 1.5 kg mass moving in a circular path is 27N

A centripetal force is a net force acting on an object in order to maintain the object's movement in a circular motion.

According to Newton's first law, it states an object will continue to proceed its movement in a straight line unless acted upon by an external force.

The centripetal force is the external force at work here and It's the net force that propels the object in a circular motion.

Using the formula for calculating centripetal force:

$\mathbf{F_c = mass (m) \times acceleration (a)}$

$\mathbf{F_c = 1.5 \ kg \times18 \ m/s^2}$

$\mathbf{F_c = 27 \ N}$

A car travels 60 miles in the first 2 hours and 68 miles in the next 2 hours

Gemiola [76]

32miles/hr

Explanation:

Given parameters:

Distance 1 = 60miles

Time 1 = 2hrs

Distance 2 = 68miles

Time 2 = 2hrs

Unknown:

Average speed of the car = ?

Solution:

Average speed is the total distance covered in a particular duration of time.

Average speed = $\frac{total distance}{total time taken}$

Total time taken = time 1 + time 2 = 2hrs + 2hrs = 4hrs

Total distance = distance 1 + distance 2 = 60miles + 68miles = 128miles

Average speed = $\frac{128miles}{4hrs}$ = 32miles/hr

What is the Difference between accuracy and precision ?<br>

Pie

Answer:

Accuracy measures how close results are to the true or known value. Precision, on the other hand, measures how close results are to one another.

An astronomer observes a hydrogen line in the spectrum of a star. The wavelength of hydrogen in the laboratory is 6.563 x 10-7m,

Sergio [31]

Answer:

D. The star is approaching Earth.

Explanation:

As we know by the doppler's effect of light that

$\frac{\Delta \nu}{\nu} = \frac{v}{c}$

here we know that

$\Delta \nu$ = change in frequency

here we know that the wavelength of light coming from the star is decreased so the frequency will increase

$\Delta \nu = \frac{c}{\lambda'} - \frac{c}{\lambda}$

$\Delta \nu =(3\times 10^8)(\frac{1}{6.56186 \times 10^{-7}} - \frac{1}{6.563 \times 10^{-7}})$

$\Delta \nu = 7.9414 \times 10^{10} Hz$

now we have

$\frac{7.9414 \times 10^{10}}{\nu} = \frac{v}{c}$

here we know that

$\nu = \frac{3\times 10^8}{6.563 \times 10^{-7}} = 4.57 \times 10^{14} Hz$

now we have

$v = 5.2 \times 10^4 m/s$

So here correct answer is

D. The star is approaching Earth.
