We can make the claim that light can be reflected, which is justified by the reflection seen on the water as well as the colors seen in the photo.

We can claim that light can and is being reflected in this image due to the reflection in the water as well as the colors. As the light traveling in the air collides with the water, it abruptly changes speed, causing a portion of these waves to be reflected back, thus creating a mirror image on the surface of the water. This is also the case with colors, which are caused by a material reflecting all but one wavelength of light.

Therefore, we can confirm that it is possible to make the claim that light can be reflected, which is justified by the reflection seen on the water as well as the colors seen in the photo.

Answer:

A. An attractive, weak force

Explanation:

I got it right

An attractive, weak force best explains the interaction between the two charges. The force between two charges is known as the Columb's force.

When the matter is put in an electromagnetic field, it has an electric charge, which causes it to experience a force. A positive or negative electric charge can exist.

Charges that are similar repel each other, whereas charges that are dissimilar attract each other. The term "neutral" refers to an item that has no net charge.

A large positive charge is placed very far away from a small negative charge. Due to the far distance, the force will be a weak force.

While due to the opposite polarity the charge is attractive in nature.

Hence an attractive, weak force best explains the interaction between the two charges

Answer:

Option B

Explanation:

See angular velocity is decreasing with respect to time , angular acceleration is negative .

The slope of the graph should be angular acceleration as slope is change in y with respect to x .

Here initial velocity made twice

so y intercept or vertical intercept should go twice up wards.

The horizontal intercept will also go twice rightwards because slope or angular acceleration is constant given .

If scale is one box=1units

Answer:

Convection is the transfer of heat from one place to another along with the motion of the object's particles. Water is a poor conductor. However, when the bottom water is heated, it turns out that the top water is also hot. This means that there is another way of transferring heat to the water, namely convection.

Explanation:

A convectional current is a process that involves the movement of energy from one place to another.

1 × 3 = 3

36 ÷ 2 = 18

18 + 3 = 21

14 × 3 = 42 you can also do 7 × 6 and will get the same result because 7 is half of 14 and 3 is half of 6

21 + 42 = 63

Explanation:

1) When we add another lamp into a series circuit, the total resistance increases, this means that the total current is the same. Also, the potential difference across each of the lamps decreases. This means that the lamps all become dimmer.

2)When we add another lamp into a parallel circuit in a new branch, the total resistance decreases, the current through each lamp decreases. Also, the potential difference across each of the lamps is the same. This means that the lamps have the same brightness.

Most of the night sky would be dark with only a few stars if the solar system were moved on the edge of galaxy.

If the Sun and Earth were moved on the edge of an elliptical galaxy, we can see most of dark and few stars in the sky at night because stars are present at large number at the center of galaxy and fewer at th edges.

So we can conclude that most of the night sky would be dark with only a few stars if the solar system were moved on the edge of galaxy.

Answer:

39.2 m/s

Explanation:

Find the time for the first one to hit the ground

h = vo t - 4.9 t^2     with h = o

0 = 49 t - 4.9 t^2       t = 10

second stone hits ground in 10 - 2 - 8 seconds

0 = vo (8) - 4.9(8)^2

vo = 39.2 m/s

When a stone is thrown vertically upwards at a velocity of 49m/s, and after 2s another stone is thrown vertically upwards,  If the two stones strike the ground at the same time the velocity with which the second stone will be 39.2 m/s.

velocity is rate of change of displacement with respect to time. it is measured in m/s.

When a stone is thrown vertically upwards acceleration due to gravity acts opposite to the velocity. At the maximum height, final velocity becomes equal to zero. hence according to kinematic equation.

v₂² = v₁² - 2as = 0

v₁² = 2as

49² = 2×9.8×s

s = 49²  ÷ 2×9.8

s = 122.5 m

This is maximum height attained by the a stone.

Time required for the first stone to attain max height,

s = ut -1/2at²

122.5 = 49t - 1/2*9.8t²

9.8t²-98t+245= 0 this is quadratic equation in t, solving it we get,

t= 5s

Total time of the flight of the first stone is 10s

According to the problem, Both the stones falls at same time, hence Total time of flight of second stone will be 10-2 = 8s

According to to projectile motion time of the flight is given by,

t = 2vsinθ ÷ g

here θ = 90°

t = 2v/g

8 = 2v/9.8

v = 8×9.8/2

v = 39.2 m/s

The velocity of the second stone with which it was thrown is 39.2 m/s.

The error in the measurement of sin 90 degrees at the given error in angle is  0.001.

The error in measurement is obtained from the difference between the actual measurement and the observed measurement.

The error of sin 90 degrees is calculated as follows;

Actual measurement = sin 90 = 1

Observed measurement = sin(90 - 0.5)

Observed measurement = sin(89.5) = 0.999

Error in measurement = Actual measurement - Observed measurement Error in measurement = 1 - 0.999

Error in measurement  = 0.001

Thus, the error in the measurement of sin 90 degrees at the given error in angle is  0.001.
