A. 866 km/h
B. 650. km/h
D. 375 km/h
C. 433 km/h

Answers

B. 650 km/h is the correct answer

The magnitude of velocity in east direction will be 650 N approximately.

What is velocity ?

velocity is given by the change in distance by the object with respect to change in time. It is a vector quantity and having S.I unit as m/s.

Here it is given that magnitude of velocity is 750 N and making an angle of 30 degree with x axis in counterclockwise direction as shown in figure below :

Now resolving and writing magnitude of velocity V in x and y direction respectively :

[tex]\begin{aligned}Vcos\theta&= 750 cos30^{o}=650 \:m/s\\Vsin\theta&= 750sin30^{o}= 375 m/s\end{aligned}[/tex]

It should be noted that [tex]vsin\theta[/tex] is acting in negative y direction.

Therefore, the magnitude of velocity in east direction is 650 m/s

How can you return a negatively or positively charged object back to its neutral state?

Answers

[tex]\huge\underline\mathtt\colorbox{cyan}{For Positively Charged:}[/tex]

By gaining electrons from the ground, the object will have a balance of charge and therefore be neutral. Grounding is the grounding of a positively charged object and involves the transfer of electrons from the ground into the object.

[tex]\huge\underline\mathtt\colorbox{red}{For Negatively Charged:}[/tex]

If it is to have its charge removed, then it will have to lose its excess electrons. Once the excess electrons are removed from the object, there will be equal numbers of protons and electrons within the object and it will have a balance of charge.

How to do this question plz answer ​

Answers

Explanation:

(i)

An analog signal has some feature that is a continuous function of the program material being transmitted. It may take on any of a range of values.

In radio, amplitude, frequency, or phase are features of the radio signal commonly modulated when transmitting an analog signal.

__

(ii)

A digital signal has some feature that is a discrete function of the program material being transmitted. It may take on any of a specific set of values.

A digital radio signal typically uses some combination of amplitude, frequency, and phase to represent a discrete state being transmitted. Only specific values of these are used by the transmitter.

(The receiver generally has to deal with corruption of the signal by the transmission channel, so the received set of values may not correlate well with those intended at the transmitter. This is why error-correcting codes are often used with digital signal transmission.)

_____

Additional comment

Analog radio signals are generally transmitted using a carrier wave at a specific frequency (or in some specific frequency range, in the case of frequency modulation). Processing techniques may be used at the transmitter to limit the bandwidth used in the transmission. One commonly-used technique is to limit the transmitted spectrum to one side of the carrier wave frequency. (This is called "single side-band" radio.)

Digital signals offer the opportunity to transmit different bits of the information at different frequencies. Sometimes, "frequency hopping" is used, so that the transmitted carrier wave jumps around from one frequency to another in a predetermined pattern. The effect of this is to spread out the spectrum of the transmitted signal so that average power in any frequency band is significantly reduced. In fact, it may be indistinguishable from background noise, except by a receiver that tunes to the carrier wave in the predetermined frequency pattern.

Two motorcycles travel along a straight road heading due north. At t = 0 motorcycle 1 is at x = 50 m and moves with a constant speed of 6.50 m/s; motorcycle 2 starts from rest at x = 0 and moves with constant acceleration. Motorcycle 2 passes motorcycle 1 at the time t = 10.08.

Part B What is the position of the two motorcycles when motorcycle 2 passes motorcycle 1? Express your answer to three significant figures and include the appropriate units.

Part C What is the acceleration of motorcycle 2? Express your answer to three significant figures and include the appropriate units.​

Answers

Answer:

Vf = 23 m/s

Explanation:

First we need to find the distance covered by the motorcycle 2 when it passes motorcycle 1. Using the uniform speed equation for motorcycle 1:

s₁ = v₁t₁

where,

s₁ = distance covered by motorcycle 1 = ?

v₁ = speed of motorcycle 1 = 6.5 m/s

t₁ = time = 10 s

Therefore,

s₁ = (6.5 m/s)(10 s)

s₁ = 65 m

Now, for the distance covered by motorcycle 2 at the meeting point. Since, the motorcycle started 50 m ahead of motorcycle 2. Therefore,

s₂ = s₁ + 50 m

s₂ = 65 m + 50 m

s₂ = 115 m

Now, using second equation of motion for motorcycle 2:

s₂ = Vi t + (1/2)at²

where,

Vi = initial velocity of motorcycle 2 = 0 m/s

Therefore,

115 m = (0 m/s)(10 s) + (1/2)(a)(10 s)²

a = 230 m/100 s²

a = 2.3 m/s²

Now, using 1st equation of motion:

Vf = Vi + at

Vf = 0 m/s + (2.3 m/s²)(10 s)

Vf = 23 m/s

jane pushed a box with 15 N force (an action) what force does the box have on Jane? which law is this?

Answers

Answer:

This is Newton’s third law (forces due to friction). There would be 15N being pushed back at Jane.

Explanation:

Newton’s third law states that for every action there is an equal and opposite reaction. So if Jane pushed with a force of 15N, 15N would be pushed back at her. Hope this helps! :)

Answers

The force of static friction acting on  the box is greater than the applied horizontal force.

Force is known to be the reason for motion according to Newton's first law of motion. An object will move when it has been acted upon by an external force.

In this case, a box lying on a table has been acted upon by an external force of  12 newton but the box remains at rest. This simply means that the applied force is less than the force of static friction acting on  the box.

a physics student throws a stone horizontally off a cliff. one second later, he throws a second identical stone in exactly the same way. which of the following statements is true?

Answers

The second stone hits the ground exactly one second after the first.

The distance traveled by each stone down the cliff is calculated using second kinematic equation;

[tex]h = v_0_yt + \frac{1}{2} gt^2[/tex]

where;

t is the time of motion [tex]v_0_y[/tex] is the initial vertical velocity of the stone = 0

[tex]h = \frac{1}{2} gt^2[/tex]

The time taken by the first stone to hit the ground is calculated as;

[tex]t_1 = \sqrt{\frac{2h}{g} }[/tex]

When compared to the first stone, the time taken by the second stone to hit the ground after 1 second it was released is calculated as

[tex]t_2 = \sqrt{\frac{2h}{g} } + 1[/tex]

[tex]t_2 = t_1 + 1[/tex]

Thus, we can conclude that the second stone hits the ground exactly one second after the first.

Using the Position vs. time Graph below, showing the motion of two cyclists (Cyclist A and Cyclist B) answer the following question.Do the two cyclists have the same velocity at t = 3 seconds?

Answers

Using the information depicted on the distance - time graph, the slope of the graph is could be used to infer the velocity of each cyclist. Hence, cyclist A and B do not have the same velocity at 3 seconds.

The steepness of slope on the distance - time graph gives the velocity of the cyclist. At time, t = 0 ; the cyclist A has a greater slope than cyclist B. Hence, the velocity of the cyclists is different.

Therefore, the cyclists do not have the same velocity at time, t = 3 seconds.
