Two waves with amplitudes of 52 units and 98 units come together. Their amplitude, which is measured at a specific point and time, is 46 units. What wave behavior explains this value? A. destructive interference B. constructive interference C. refraction D. diffraction E. partial transmission

Answers

Answer 1

Answer: A

destructive interference

Explanation: Interference involves coming together of two waves of the same type. E.g sound waves, water waves e.t.c

Whenever two waves of different amplitude interferes with one another and there is increase in amplitude, this is known as constructive interference.

But whenever there is decrease in amplitude as a result of interference of the two waves, this is known as destructive interference.

If Two waves with amplitudes of 52 units and 98 units come together. Their amplitude, which is measured at a specific point and time, is 46 units. The wave behavior that explains this value is destructive interference because of decrease in the units of amplitude.

A golfer is teeing off on a 130.0 m long par 3 hole. The ball leaves with a velocity of 35.0 m/s at 35.0° to the horizontal. Assuming
that she hits the ball on a direct path to the hole, how far from the hole will the ball land (no bounces or rolls)?

Answers

Answer:

The ball will land 12.5m before that hole.

Explanation:

The motion of the golf ball can be considered as a projectile motion, where first its height is 0, then it keeps increasing to a maximum point, after which its height starts decreasing again and hits the ground (height becomes 0 again).

We need to calculate the Range (horizontal distance) of the ball which is given as:

[tex]R=\frac{v_i^2{\cdot}sin2\theta}{g}[/tex]

Where

v(i) = initial velocity = 35 m/s

θ = Initial angle = 35°

g = gravitational acceleration = 9.8 m/s

Substitute in the given formula to find Range:

[tex]R=\frac{(35)^2\cdot{sin}(2)(35)}{9.8}\\R=\frac{(1225)(0.94)}{9.8}\\R = 117.5~m[/tex]

Distance between the hole and position where ball lands = 130m - 117.5m = 12.5m

Answer:

The fundamental wavelength of the vibrating string is 1.7 m.

Explanation:

We have,

Velocity of wave on a guitar string is 344 m/s

Length of the guitar string is 85 cm or 0.85 m

It is required to find the fundamental wavelength of the vibrating string. The fundamental frequency on the string is given by :

[tex]f=\dfrac{v}{2l}\\\\f=\dfrac{344}{2\times 0.85}\\\\f=202.35\ Hz[/tex]

Now fundamental wavelength is :

[tex]\lambda=\dfrac{v}{f}\\\\\lambda=\dfrac{344}{202.35}\\\\\lambda=1.7\ m[/tex]

So, the fundamental wavelength of the vibrating string is 1.7 m.

If the billing cycle length for a credit card is one calendar month, which of the
following months will result in the greatest periodic interest rate?
O A. December
B. June
C. April
!!!2O D. September​

Answers

Answer: A.) December

Explanation:

December has the highest number of days in the options given above, with 31 days compared to the others with 30 days within a calendar month. The billing cycle is used to refer to a time interval between the end and the next billing or statement date. In the scenario above, the billing cycle length is monthly, meaning the periodic interest will be paid over a 31 day span time before thre beginning of another cycle.

For example, if periodic interest is $1 per day, this amount totals ($1 × 31) in december compared to the ($1 × 30) Interest in the June, April and September billing cycle.

6. The peak value of an AC sine wave is
120 V. What's the effective value
(rounded)?
A. 65 V
B. 85 V
C. 200 V
D. 140 V

Answers

Answer:

B.  85  V

Explanation:

E(rms) = E(peak-to-peak) / squareroot(2)

E(rms) = 120V / 1.414 = 84.9 V

(When  rounded)  =  85  V

The correct option about peak value and effective value of AC sine wave is, “85 V”.

What are the differentiating factors between peak value and effective value?Peak value is also known as maximum value.Effective value is also known as RMS (Root Mean Square) value.Maximum value attained by Alternating quantity is defined as Peak value.The square root of average of the square of quantity during a complete cycle is defined as Effective Value.

How to do the conversion between peak value and effective value?To convert peak value to effective value, divide the peak value by √2 and the result will be the effective value.To convert effective value to peak value, multiply the effective value with √2 and the result will be the peak value.

How to solve this question?

Peak value = 120 V (Given)

Effective value = Peak value ÷ √2

Effective value = 120 ÷ √2

Effective value = 85 V (approximately)

Thus, we can conclude that by dividing the peak value by √2, we will get effective value and multiplying the effective value with √2 will give peak value as result.

Remembering the Battle of Bunker Hill what did general Howe and his troops do

Answers

Answer:

General Howe and the British regrouped after losing the hill.

Explanation:

British forces marched to Breed's Hill on 17 June under the order of Major General William Howe. When the British Army marched in waves toward the Americans, Colonel William Prescott issued orders to avoid the fire until British troops came to clear sight in an attempt to protect the dwindling supply of ammunition to the Americans. Many British soldiers have been killed or maimed; the remainder has withdrawn down the hill. In a second wave, the British stormed the hill once again but met with the same fate. So they withdrew again, suffering a large number of casualties.  Eventually the British took the hill in the third attempt but at a great cost of casualties.

hi:) is question 6 correct?

Answers

-- When you see the words "uniform speed", that means the car's speed is not changing.  

-- Right under those words in the picture, there's a note to remind you that "uniform speed" also means "acceleration is zero".

-- The whole key to this question is to find out if you remember that acceleration and net force always go together.  

.==> If there's net force, then there's acceleration.

.==> If there's acceleration, then there's net force.  

.==> If there's NO net force then there's NO acceleration.

.==> If there's no acceleration, then there's no net force.

-- In this picture, there's no acceleration, so there's no net force.

-- The driving force on the car is 2000N forward.

-- But the car's speed is not changing, so the net force on the car must be zero.

-- So that 'resisting' force pulling the car backwards must be 2000N. Then the net force on the car adds up to zero.

-- If the resisting force pulling the car backwards is not zero, then the net force on the car would not be zero, and the car's speed would be changing.

hope it helps you make me as brainlylist

Potential energy will be greatest at the points A and G, and kinetic energy will be greatest at the point D.  

• The energy possessed by an object due to its motion is termed as the kinetic energy. On the other hand, the energy stored within an object because of its position relative to some zero position is known as the potential energy of the object.  

• Kinetic energy is highest when the velocity is the highest, in the case of pendulum, this takes place at the bottom. In the given case, that is, at point D.  

• If kinetic energy is highest at point D, then at the same point potential energy will be the lowest.  

• Therefore, potential energy would be highest at its highest point on each of the side of its motion where it remains stationary for some time, that is, at point G and A.  

Thus, kinetic energy would be highest at point D, and potential energy would be highest at the points A and G.

USANDO LA SEGUNDA LEY DE NEWTON:

m = 80.0 N/[tex]9.80 m/s^{2}[/tex] = 8.16 kg

Answer:

8kg

Explanation:

using the formula Force(F)=mass(m)×acceleration(a),

since we are finding the mass of the object,we will make m the subject by dividing both sides by a.

you will now get m= f/a

the acceleration on Earth is usually 10m/s

m= 80/10

m= 8/1 which is also 8kg
