Answer and Explanation:

Using a = F/m, we get:

Acceleration for Road A = 480/62 = ~7.74 m/s^2

Acceleration for Road B = 240/62 = ~3.87 m/s^2

Acceleration for Road C = 600/62 = ~9.68 m/s^2

If the net force becomes higher than 600N and the mass stays constant, the acceleration will increase proportionally to how much the force increases and the acceleration will be greater than the acceleration when the force is 600N.

I hope this helps! :)

Make vector A on the simulation have a magnitude of exactly 10 units. What were the starting points and ending points of your ve

Gwar [14]

Answer:

Making a vertical vector, we have a starting point at (-5,2) and an end point at (5,2) that will give us a vector of magnitude of 10 units.

Explanation:

In order to make vectors that have a magnitude of 10 units, the distance between the starting and ending points must be equal to 10.

The easiest way is to set points on either an horizontal or vertical line to make horizontal or vertical vectors.

We can have starting point at (-5,2) and then move up 10 units so we will be at the ending point (5,2), thus the distance between them is 10 units so the vector has a magnitude of 10 units.

We can verify that using the formula for the magnitude which requires first to find the vector.

$\vec v = \text{End point } - \text{Start point}$

So for the points we have

$\vec v = (5,2)-(-5,2)$

We can work with each component, for the x component we have 5-(-5) which give us 10 and for the y component we have 2-2 which give us 0, so the vector is

$\vec v =$

Thus its magnitude is

$|v|= \sqrt{v_x^2+v_y^2}\\|v|= \sqrt{10^2+0^2}\\|v|=\sqrt{100}\\|v|=10$

Thus we have verified our vector has a length 10.

The sideview mirrors on cars are convex mirrors. Let's say the mirror on the driver's side of your car has a focal length with a

Arisa [49]

Answer:

a) i = -2.53 m , b) m = 0.63

Explanation:

a) For this exercise we use the constructor equation

1 / f = 1 / o + 1 / i

Where f is the focal length, o the distance to the object and i the distance to the image

In this exercise they give the focal length f = -6.90 m, the negative sign is a convex mirror, and the distance to the object is o = 4.00 m

Let's find the distance to the image

1 / i = 1 / f - 1 / o

1 / i = 1 / -6.90 - 1/4

1 / i = -0.1449-0.25 = 0.3949

i = -2.53 m

.b) the expression for the magnification is

m = - i / o

m = - (-2.53) / 4

m = 0.63

The wavelength of a sound in a certain material is 18 cm the frequency of a wave is 2000 Hy calculate the speed of the wave

Leokris [45]

Answer:

Speed = 360m/s

Explanation:

Given the following data;

Wavelength = 18cm to meters = 18/100 = 0.18m

Frequency = 2000Hz

To find the speed;

Speed = frequency * wavelength

Speed = 2000 * 0.18

Speed = 360m/s

Therefore, the speed of the wave is 360 meters per seconds.
