Answer:

The resultant velocity and direction of the plane with respect to the ground is 704 km/h due east.

Explanation:

Given that,

Air velocity v₁= 720 km/h

Headwind v₂ = 16 km/h

The air velocity due to east is greater then the head wind.

So, the direction of the velocity respect to the ground will be due to east.

The velocity of plane respect to ground

The resultant velocity will be

Hence, The resultant velocity and direction of the plane with respect to the ground is 704 km/h due east.

If it is a headwind it means it's travelling against the motion of the plane. This means it's velocity is simply v=720-16=704 km/h due east.

Solution 2

Answer: The statements B and D are correct answers.

Explanation:

Work is done when the force is applied to an object then there will be displacement by the object.

In the option A,  Hannah leans against her locker, but it doesn’t move. There is no displacement in this case. The work done is said to be zero in this case.

In the option B,  Andy’s car rolls down a hill with the engine off. There is displacement in this case. The work is said to done in this case. At the hill, the car has a maximum potential energy.

When it rolls down then the kinetic energy of the car will increase. From the work energy theorem, the change in the kinetic energy is equal to the work done.

In the option C, A wind turbine stands still on a sunny, windless day.  The work done is said to zero in this case.

In the option,  A balloon expands as it is heated by the Sun. There is expansion of the balloon. The work is done in this case as the volume and the pressure will also increase on heating the balloon.

In the option E, James pedals a stationary exercise cycle that doesn’t move. No work is done in this case.

Therefore, the statements B and D are correct answers.

Question
Which situation best describes the act of reducing? paying bills online instead of sending paper through the mail donating gently used clothes and household items using plastic bags a second time to avoid buying new ones buying products that can be recycled so they don’t end up in the trash
Solution 1

Answer:

paying bills online instead of sending paper through the mail

Explanation:

In today's era everyone is aware about the Climate change and wants to contribute towards environment protection. A simple technique is to follow four R's which are: Reduce, Reuse, Recycle and Refuse. The four examples given over here are examples of each R as explained below:

Reduce:  paying bills online instead of sending paper through the mail as we are reducing the paper use over here.

Reuse: donating gently used clothes and household items so that they can be reused. Using plastic bags a second time to avoid buying new ones.

Recycle & Refuse: buying products that can be recycled so they don’t end up in the trash

Question
If a car travels 30 mi. north for one-half hour, 50. mi. east for one hour, and 30 mi. south for 30 min., what is the total distance the car traveled?
Solution 1

Answer:

110 mi

Explanation:

d1 = 30 mi, d2 = 50 mi, d3 = 30 mi

Distance is defined as the length of actual path traveled.

So, total distance, d = d1 + d2 + d3 = 30 + 50 + 30 = 110 mi

Solution 2
50 miles to the east hope it helps
Question
A 45 kg student runs up a flight of stairs that are 3.2 m high in 2 seconds. How much power did the student use during this time? 706 W 288 W 72 W 7.0 W
Solution 1

The power used by the student is equal to 706.32 W. Therefore, option A is correct.

### What is power?

The power can be demonstrated as the rate of doing work and can be defined as the work done in unit time. The SI unit of power can be expressed as joules per second (J/s) or Watt.

Power can be described as a time-based parameter and the rate at which work is done on a body. The mathematical formula for power can be represented as mentioned below.

Power = Work/ time

P = W/t

Given, the mass of the student, m = 45 kg

Consider, the height of the stairs, h = 3.2 m

The work done by the student, W = mgh,

W = 45 × 9.81 × 3.2

W = 1412.64 J

The power used by the student, P = W/t

P = 1412.64/2

P = 706.32 W

Therefore, the power did the student use during this time is 706.32 W.

Solution 2
Power = work done/time. Work done by gravity = mgh = 45x9.8x3.2 = 1411.2J. Therefore, power = 1411.2/2 = 705.6 ~ 706W.

A 6000 kg train car traveling at 2.5 m/s collides with another 6000 kg train car, now they are both moving but with a speed of 1.25 m/s. This is an example of Conservation of Momentum.You can prove it by (6000kg)(2.5m/s)+(6000kg)(0m/s= (6000+6000kg)(1.25m/s).

Hope this helps :)

Question
A person on a cruise ship is doing laps on the promenade deck. on one portion of the track the person is moving north with a speed of 3.8m/s relative to the ship. the ship moves east with a speed of 12m/s relative to the water. what is the direction of motion of the person relative to the water?
Solution 1

The two components of the motion (3.8 m/s north and 12 m/s east) correspond to the two sides of a right triangle, where 3.8 is the length of the vertical side while 12 is the length of the horizontal side. Therefore, the angle which gives the direction of motion is given by

where vx is the horizontal velocity and vy is the vertical velocity. Substituting numbers into the equation, we find

so, 17.6 degrees north of east.

Solution 2
The resultant motion is given by pithagoras, since the two components (north and east) are perpendicular to each other.
They are asking you about the direction so you have to use trigonometry, finding that the direction is Ф=arctan(3.8/12)=17.57° north of east.
