current to flow in the circuit
O B it is best to replace it with a much larger fuse
o you should replace the fuse and check to see what might have

O the circuit catches fire

Answers

Answer:  A

it's a sign that there might be something causing too much

current to flow in the circuit

Explanation: When a fuse blows, one of the causes may be short circuit. Also, it's a sign that there might be something causing too much

current to flow in the circuit leading to overloading. That is, drawing to much of power that can cause the metal inside the fuse to melt.

Option A is the best answer.

A lens with f= 10.0 cm is held
45.0 cm from an object. What is
the image distance?
(Unit = cm)
it is not 12 cm.

Answers

Answer:

8.2 cm

Explanation:

1/f = 1/so + 1/si

1/10 = 1/45 + 1/si

1/si = 1/10 - 1/45

1/si = 9/90 - 2/90

1/si = 7/90

si = 90/7 = 12.86 cm.

since you said that the answer was not 12 them the lens must be concave with negative (minus) focal length

1/f = 1/so + 1/si

- 1/10 = 1/45 + 1/si

1/si = - 1/10 - 1/45

1/si = -9/90 - 2/90

1/si = -11/90

si = -90/11 = - 8.2 cm

- (read: minus or negative sign) indicates the image is in the same side of the object

hope its true and can help you

Answer:

1/f = 1/u + 1/v

f=10cm

u=45cm

v=? (Image distance)

1/v = 1/f - 1/u

1/v = 1/10 - 1/45

1/v = (9-2)÷ 90

1/v = 7/90

:. v = 90/7

v=12.86cm(image distance)

A car of mass 1000kg is moving at a speed of 20m/s.
It's brought to rest at a distance of 50m. Calculate the net force acting on the car. ​

Answers

Answer:

-4000 N

Explanation:

1. First let's look at what we know.

Mass: 1000 kg

Initial velocity: 20 m/s

Final velocity: 0 m/s

Displacement: 50 m

2. Let's try and apply a Kinematics equation here.

Looking at what information we have, I would say that this is the best equation:

v[tex]f^{2}[/tex]=v[tex]o^{2}[/tex] + 2aΔx

3. Plug in the numbers.

0 = 400 + 2(a)(50)

0 = 400 + 100a

-400 = 100a

a = -4 m/s^2

4. Use ∑F=ma

∑F = (1000)(-4)

∑F = -4000 N

Which of the following is the best description of the term resultant
displacement?
A. The scalar that joins all the points along the path.
B. The average of all the displacement vectors.
C. The total distance traveled.
O D. The shortest distance from the beginning point to the end point.

Answers

Answer:

D

Explanation:

Displacement refers to the shortest, or straight-line path from one point to another. It is a vector, thus A is incorrect. It is not the average, but rather the sum of all displacement vectors, so B is incorrect. It is not the distance traveled, as some paths have longer distances than others, while leading to the same destination, hence same displacement. (i.e. running around in circles yields positive distance traveled but zero displacement.)

Answer:

Explanation: D

Displacement is a vector. It has direction and it has magnitude. But we are asked for the resultant displacement. You have to use pythagorean theorem. This makes our answer always positive. That essentially means distance, since you did just do the distance formula.

A is wrong because that tells you perimeter

B is wrong because that tells you the midpoint

C is wrong because displacement and distance are two different things. We dont want the distance of the two vectors

D is correct, this perfectly explains the distance formula

A negative slope on the velocity vs. time graph indicates that the object is not

A. True
B. False

Answers

Answer: False, I think

Explanation:

Well it depends. Its hard to say without a function of the graph. Given a velocity graph, the first derivative is the acceleration.

Negative slope on a velocity graph means you are going in the negative direction. And over time, your velocity per unit of time is also decreasing. That means we are accelerating in the negative direction

False, your velocity would just be in the negative direction.

Describe the relationship between frequency and wavelength

Answers

Answer:

Frequency and wavelength are inversely related.

Explanation:

Frequency and wavelength have an inverse relationship because if one thing goes up another goes down. For example, if frequency goes up, the wavelength goes down and vice versa.

Answer:

The relationship between wavelength and frequency is that the frequency of a wave multiplied by its wavelength gives the speed of the wave.

Explanation:

Frequency and wavelength are related terms also, used to describe electromagnetic radiation or light. One simple equation is used to convert between them: frequency x wavelength = speed of light. λ v = c, when λ is wavelength, v is frequency, and c is the speed of light.

A ball is dropped from a height of 23.5 meters. Assuming no air resistance, how many seconds will it take the ball to hit the
ground?

Answers

Answer:

About 2.19 seconds

Explanation:

[tex]d=v_ot+\dfrac{1}{2}at^2[/tex]

Since the ball is dropped from rest, there is no initial velocity, and you can write the following equation:

[tex]23.5=\dfrac{1}{2}(9.8)t^2 \\\\t^2\approx 4.79 \\\\t\approx 2.19s[/tex]

Hope this helps!

It will attain a speed of 20m/s before touching the ground, but the time taken to reach the ground is 2 seconds. Because the velocity is not uniform but acceleration/gravity is. Therefore, the answer to your question is: 2 seconds.

8. How does the direction of friction compare to an object's direction of motion?

Answers

Answer: The direction of the force of friction is such that it opposes the direction of motion that an object would move if there were no frictional force acting on the object.

The direction of motion and direction of friction have to be  in opposite directions for a object to be in motion.

What is motion?

Motion is defined as a phenomenon which is described with respect to change in object's position with respect to time.It is given in terms of displacement,velocity,distance ,acceleration,speed.

Branch of physics which deals with motion of objects without any reference to it's cause is called kinematics while the branch which studies forces and their effects on motion is called as dynamics.

Motion applies to various systems like objects,bodies, matter particles ,radiation ,curvature.There are three laws of motion which are proposed by Newton.Classical mechanics is based on Newton's law of motion.Relativistic  mechanics is based on modern kinematics.

Answers

Answer: d

One thirty-sixth of

Explanation: Gravitational field or gravitational field strength obeys the inverse square law. The gravitational field is inversely proportional to the square of the earth distance. That is,

g = Gm/r^2

Where r = distance.

If weather satellite is placed in orbit six times farther away from the earth's centre, gravitational field will be one thirty-sixth of its initial value.

Therefore, the gravitational field experienced by the satellite in orbit is one thirty-sixth of the field that it experienced on the ground.

the force of attraction between two masses is 3.60 Newtons if one of the masses is tripled and the distance between the masses is quadrupled what is the new force of attraction​

Answers

Answer: F = 19.2 N

Explanation: Given that the initial Force = 3.6N

The formula involved is

F = GMm/r^2

Substitute the force F

3.6 = GMm/r^2

If one of the masses is tripled and the distance between the masses is quadrupled. We have

3.6 = (G × 3Mm)/(4r)^2

Where G will be constant.

3.6 = 3GMm/16r^2

Separate the fraction of number

3.6 = 3/16 × GMm/r^2

Make GMm/r^2 the subject of formula

(3.6 × 16)/3 = GMm/r^2

19.2 = GMm/r^2

Therefore, the new force of attraction is 19.2 N

Answers

Answer:

11.) g = 3.695 m/s^2

12.) g = 8.879 m/s^2

13.) E = 8127 N/C

Explanation:

11.) Given that the

Mercury mass M = 3.3 × 10^23kg

Radius r = 2.44 ×10^6 m

Gravitational constant G = 6.67408 × 10^-11 m3kg-1 s^-2

Gravitational field strength g can be calculated by using the formula below

g = GM/r^2

Substitutes all the parameters into the formula

g = (6.67408 × 10^-11 × 3.3 × 10^23)/(2.44×10^6)^2

g = 2.2×10^13/5.954×10^12

g = 3.695 m/s^2

12.) Given that the

Venus mass M = 4.87×10^24kg

Radius r = 6.05 × 10^6 m

Using the same formula for gravitational field strength g

g = GM/R2

Substitute all the parameters into the formula

g = (6.67408 × 10^-11 × 4.87×10^24)/(6.05×10^6)^2

g = 3.25×10^14/3.66×10^13

g = 8.879 m/s^2

13.) Given that the

Charge = 2.26 nC = 2.26×10^-9

Distance d = 0.05m

Electric field strength E can be calculated by using the formula below

E = Kq/d^2

Where

K = electrostatic constant 8.99 × 10^9 Nm2/C2

Substitutes all the parameters into the formula

E = (8.99 × 10^9 × 2.26×10^-9)/0.05^2

E = 20.3174/2.5×10^-3

E = 8126.96 N/C
