Question 1 (1 point)

Physics
1 answer:
TiliK225 [7]3 years ago
3 0

Answer:

The resultant velocity of the plane relative to the ground is;

150 kh/h north

Explanation:

The flight speed of the plane = 210 km/h

The direction of flight of the plane = North

The speed at which the wind is blowing = 60 km/h

The direction of the wind = South

Therefore, representing the speed of the plane and the wind in vector format, we have;

The velocity vector of the plane = 210.\hat j

The velocity vector of the wind = -60.\hat j

Where, North is taken as the positive y or \hat j direction

The resultant velocity vector is found by summation of the two vectors as follows;

Resultant velocity vector = The velocity vector of the plane + The velocity vector of the wind

Resultant velocity vector = 210.\hat j  + (-60.\hat j) =  210.\hat j  - 60.\hat j = 150.\hat j

The resultant velocity vector = 150.\hat j

Therefore, the resultant velocity of the plane relative to the ground = 150 kh/h north.

What accounts for the two precipitation peaks in mbandaka?
slava [35]

The two precipitation peaks in Mbandaka during March to April and September to November is due to the intertropical convergence zone.

Intertropical convergence zone is a narrow zone located near the equator. It is where the northern and southern air masses intersect which results to low atmospheric pressure. Due to the intertropical convergence zone’s meeting of air masses, often times the air pressure are lower which will results to colder air, or even rainfall during the period of March to April, and most especially September to November in Mbandaka.

<span>Since Mbandaka is located at the cented of Tumba-Ngiri-Maindombe area, which is named as a Wetland of International importance, there is really a bigger chance that this place experience above 60mm precipitation in a year, temperatures averaging from 23 – 26 degrees Celsius.</span>

An airplane flying at a velocity of 610 m/s lands and comes to a complete stop over a 53 second period of time.
Airida [17]

Answer:

a = - 11.53[m/s^2]

Explanation:

The airplane slows down as its speed decreases from the initial value of 610 [m/s] to zero.

To calculate the acceleration value we use the following kinematics equation:

v_{f} = v_{i}+(a*t)\\

where:

Vf = final velocity = 0

Vi = initial velocity = 610 [m/s]

a = acceleration [m/s2]

t = time = 53 [s]

Now replacing:

0 = 610 + (a*53)

-610 = 53*a

a = - 11.53[m/s^2]

The negative sign means that the aircraft is losing speed, i.e. slowing down

Warm air and water rise because...
Igoryamba
We know that an object floats in a fluid if the density of the object is less than the density of the fluid. When some air or water is heated, it expands. That makes its density less than cooler air or water, so it floats in them.
