Explanation:
the diagram shows a ray of light being reflected by a plane mirror and one angle is 60 degrees.what will be the measure of its angle of incidence and angle of reflection?
Answer:
when the light is reflected from a surface the angles of incident is always equal to the angles of reflected where both angles are measures from the path of the light to the normal to the surface at the point at which light stricks the surface . this equality is known as the law of reflection .
Since the angle of reflection is 60 degrees, the angle of incidence is also 60 degrees.
What are the laws of reflection?The laws of reflection describe the behavior of light when it is reflected off a smooth surface, such as a plane mirror. There are two laws of reflection:
1. The angle of incidence is equal to the angle of reflection: When a light ray strikes a surface, the angle between the incoming ray and the surface (the angle of incidence) is equal to the angle between the reflected ray and the surface (the angle of reflection). This law holds true for all angles of incidence.
2. The incident ray, the reflected ray, and the normal to the surface all lie in the same plane: The normal is an imaginary line perpendicular to the surface at the point where the ray strikes the surface. The incident ray is the incoming ray of light, and the reflected ray is the ray that bounces off the surface. Both of these rays, along with the normal, all lie in the same plane.
These laws can be used to predict the path of reflected light and to determine the position and size of an image formed by a plane mirror. The angle of incidence and angle of reflection can be measured using a protractor, and the normal can be found by drawing a line perpendicular to the surface at the point of incidence.
Here in the Question,
According to the law of reflection, the angle of incidence (i) is equal to the angle of reflection (r), which means:
i = r
The angle of incidence = Angle of reflection = 60 degrees.
Therefore, The angle of incidence is also 60 degrees since the angle of reflection is 60 degrees.

High blood pressure can lead to all of the following except: Question 3 options: A) stroke B) vision loss C) aerobic fitness D) heart attack
Answer:
C) Aerobic Fitness
Explanation:
High blood pressure doesn't affect your aerobic fitness.
High blood pressure can lead to stroke, vision loss, and heart attack except in aerobic fitness. Therefore, option (D) is correct.
What is High blood pressure?High blood pressure can be described as a condition in which the force of the blood against the artery walls is too high. Usually, hypertension can be defined as blood pressure above 140/90 and can be severe if the pressure is above 180/120.
High blood pressure generally develops over time. It can occur because of an unhealthy lifestyle, or not getting enough physical activity. Certain health conditions, such as diabetes can also increase the risk of leading to high blood pressure. In high blood pressure, the force of the blood pushing against the artery walls is too high and the heart works harder to pump blood.
High blood pressure has no common symptoms. Over time, if untreated, it can cause health conditions like heart disease and stroke. Eating a healthy diet with less salt, regularly exercising, and taking medications can lower blood pressure.

1.Round off the following measurement to the three significant figures. 1.296 g.
2. How many significant figures are there in the following measurement? 2020 g.
3.Round off the following measurement to the three significant figures. 5.658 grams
Answer:
1) 1.30g2) 3 sf3) 5.66 gramsExplanation:
1) Significant figure means the amount of figure we are interested in. Note that 0 is insignificant. For example 30 is a one significant figure i. e the only figure of interest is 3.
Given the figure 1.296 g, as we can see, there are initially for figures in the value. This means we are to eliminate one to make it 3. To do that we will remove the 6 at the back by round it up to 1 and add it to the value of 29 preceding it to give 30. The figure will become 1.30 (to 3sf).
Note that only values greater than 4 are rounded up to 1 and added to the preceding value
2) Given the figure 2020, the number of significant figures present is 3 significant figure. Note that all zeros at the end of a value are considered insignificant hence the only significant value here is 202 (which is 3 sig fig.)
3) For the figure 5.658, the value to 3sf is 5.66 (Note that the value of 8 at the end is rounded up to 1 and added to 65 to make it 66). This is as explained in the first answer above.

(4. A bus is moving at 25 m/s when the driver steps on the brakes and brings the bus to a stop in
3.0 s.
a. What is the average acceleration of the bus while braking?
b. If the bus took twice as long to stop, how would the acceleration compare with what you
found in part a?
Answer:
(a) the average acceleration of the bus while braking is 8.333 m/s
(b) if the bus took twice as long to stop, the acceleration will be half of the value obtained in part a. [¹/₂ (8.333 m/s) = 4.16 s]
Explanation:
Given;
initial velocity of the bus, v = 25 m/s
time of the motion, t = 3 s
(a) the average acceleration of the bus while braking
a = dv/dt
where;
a is the bus acceleration
dv is change in velocity
dt is change in time
a = 25 / 3
a = 8.333 m/s
(b) If the bus took twice as long to stop, the duration = 2 x 3s
a = 25 / (2 x 3s)
a = ¹/₂ x (25 / 3)
a = ¹/₂ (8.333 m/s) = 4.16 s
Thus, if the bus took twice as long to stop, the acceleration will be half of the value obtained in part a.
(a) The average acceleration of the bus while braking is 8.333 m/s.
(b) In the case when the bus took twice as long to stop, the acceleration will be half of the value obtained in part a. [¹/₂ of 8.333 m/s) = 4.16 s]
Calculation of acceleration:initial velocity of the bus, v = 25 m/s
time of the motion, t = 3 s
(a) the average acceleration of the bus should be
a = dv/dt
Here,
a is the bus acceleration
DV is a change in velocity
dt is changed in time
So,
a = 25 / 3
a = 8.333 m/s
(b) If the bus took twice as long to stop, the duration = 2 x 3s
So,
a = 25 / (2 x 3s)
a = ¹/₂ x (25 / 3)
a = ¹/₂ (8.333 m/s)
= 4.16 s

Three identical resistors of resistances 5Ω, 10Ω and 30Ω are connected with a battery of 12V[tex].[/tex]
To Find :We have to find current through the each resistor and equivalent resistance of circuit[tex].[/tex]
SoluTion :➝ Equivalent resistance of series connection is given by
R = R1 + R2 + R3➝ We know that, Equal current flow through each resistor in series connection.
➝ As per ohm's law, Current flow through a conductor is directly proportional to the applied potential difference.
V = IR◈ Equivalent resistance :
⇒ Req = R1 + R2 + R3
⇒ Req = 5 + 10 + 30
⇒ Req = 45Ω
◈ Current flow in circuit :
⇒ V = IReq
⇒ 12 = I × 45
⇒ I = 0.27A
፨ Therefore, 0.27A current will flow through each resistor.

An atom with the expected number of neutrons, protons, and electrons is called a(n)
Answer:
Stable atom
Explanation:
A stable atom is one that has a balanced nuclear inter-particle force reaction as such the binding energy of a stable atom is sufficient to permanently keep the nucleus as one unit. Examples of a stable atom are the atoms of monoisotopic elements such as fluorine, sodium, iodine, gold, aluminium, and cobalt.
In a stable atom the expected number of proton, neutron, and electron are present while in an unstable atom or radioactive atom, there are more than the expected number of neutrons or protons, such that the internal energy of the nucleus is excessive and more than the binding energy, which can lead to radioactive decay.

The distance walked by the football coach eastward = 24 meters
The distance walked by the football coach westward = 12 meters
Then the distance walked by the football coach eastward = 36 meters
Finally, the distance walked by the football coach westward = 22 meters
The total distance walked by the coach eastward = 24 + 36 = 60 meters
The total distance walked by the coach westward = 12 + 22 = 34 meters
Taking x-direction as positive, we have;
The magnitude of the distance = 60 - 34 = 24 meters,
The direction of the coach = Eastward.
