The answer is -7m, but I don’t know how that’s the answer. Can anyone explain?

Answers

Explanation:

At first it is in 14m position but position doesn't matter in displacement, similar case for time taken.

So at first it travels 6m in positive direction.

So displacement= 6m

Then it travels 13 in opposite or negative direction.

So displacement = 6 -13 m = -7 m

a typical 100-watt light bulb consumes 100 j of energy per second. if a light bulb converts all of this energy to 400 nm light, how many photons are produced each second?

Answers

Answer:

Let y equal lambda the wavelength of the light

e (photon) = h f = h c / y

e = 6.63E-34 * 3.0E8 / 400E-9

e = 6.63 * 3  / 400 * 10^-17

e = 4.97E-19

N= 100 J/sec/ 4.97E-19 J = 2.01E20 / sec

Find the instantaneous acceleration at t=ls for an object moving along a straight axis with velocity function:
v(t)= -t3+5t

Answer:

A. 2m/s^2

B. 5m/s^2

Answers

The answer is A.
Explanation:
We know that the average acceleration a for an interval of time Δt is expressed as:

a = Δv
Δt
where Δv is the change in velocity that occurs during Δt.
e formula for the instantaneous acceleration a is almost the same, except that we need to indicate that we're interested in knowing what the ratio of Δv to Δt approaches as Δt approaches zero.

We can indicate that by using the limit notation.

So, the formula for the instantaneous acceleration is:

a = lim Δv
Δt→0 Δt

an object is moving forward with a constant velocity. which statement about this object must be true?

Answers

Answer:

• Its acceleration is zero

Explanation:

from definition of acceleration:

[tex]{ \rm{acceleration = \frac{change \: in \: velocity}{time} }} \\ \\ { \rm{acceleration = \frac{ \delta \: (velocity)}{time} }}[/tex]

• since velocity is constant, change in velocity is zero

[tex]{ \boxed{ \rm{ \delta \: (velocity) = 0}}}[/tex]

• therefore:

[tex]{ \rm{acceleration = \frac{0}{time} }} \\ \\ { \boxed{ \tt{acceleration = 0 \: m {s}^{ - 2} }}}[/tex]

Blue bumper car, traveling east with a force of 100 N, runs into a yellow bumper car traveling west with a force of 300 N. Because the net force will be -200 N. one of the cars will be pushed backward. Which one?

Answers

Answer:

the blue bumper car

Explanation:

because the yellow bumper car is coming in with much more force

and according to Newton, actions and reactions are equal and opposite, so the yellow bumper car will five out 300N while the blue car will give out only 100N

then it almost because a fight between 300N vs 100N

and obviously, the 300N will win and the 100N will be pushed back

Dark matter pulls the moon around earth in a circular pattern

Answer:

The moon is being pulled to the earth by gravity, so the net force makes a circular pattern.

Explanation:

The force of gravity is a force that pulls objects toward the centre of the earth. The acceleration due to gravity of the moon is about 1.6 metre per second square which is comparatively smaller than the earth's 10metre per second. Therefore, the moon isn't completely pulled to the centre of the earth, but orbits around the earth

Surveyors frequently use trig functions. Suppose that you measure the angle from your position to the top of a mountain to be 2.50∘. (Figure 6) If the mountain is 1.00 km higher in elevation than your position, how far away is the mountain?

Answer:

22.9km

If the mountain is 1.00 km higher in elevation than your position and the angle measured from your position to the top of a mountain is 2.50∘.then you would have been 22.9 km far away from the mountain

What are trigonometric functions?

A right-angled triangle's side ratios are the easiest way to express a function of an arc or angle, such as the sine, cosine, tangent, cotangent, secant, or cosecant. These functions are known as trigonometric functions.

As given in the problem you measure the angle from your position to the top of a mountain to be 2.50∘. If the mountain is 1.00 km higher in elevation than your position,

By using the tangent trigonometric function for the right triangle

tanθ = height /distance

tan 2.5° = 1000 m /distance

distance =1000 m /tan 2.5°

              =22903 m

              =22.9 km

Thus, the mountain is 22.9 km far away from your position

3 situations that give friction a “bad reputation”​

Answers

Friction raises negative thoughts in most designer’s minds. When you ask designers about friction, most of them will tell you that friction damages a UX because it slows down interactions, reduces conversions, and impedes progress. Today frictionless design is the new business goal. Designers seem to be obsessed with the idea of going from A to B in the fastest, smoothest and most efficient way. A good example is the popular Amazon physical dash button, that allows users to order a refill of a specific product in just one click.

a. Define displacement
b. Use the definition of displacement to explain how it is possible for an athlete to run round a track yet have no displacement

Answers

Answer:

definition: the moving of something from its place or position.

Explanation:

though moving around a track they will always end in the same place therefore there is no displacement from the beginning position

There is no displacement from the starting position because they will always wind up in the same place as they started.

What is displacement?

Displacement is defined as the overall alteration of an object's location and motion direction. Displacement is recognized as a vector quantity since it takes into account both the direction of the motion and the magnitude of the changing position. Displacement may be zero, positive, or negative.

The initial and final positions are needed in order to calculate displacement because displacement does not provide comprehensive information on the full path length.

The displacement is the shortest distance from the starting point to the finish point, the athlete starts from the start line and reaches the finish line after running through the whole track, but the starting point and the finishing point are the same, so the displacement is zero.

Therefore, the displacement of the athlete running through the track is zero for a complete race.
