Answer:
The truck must travel at a speed of 98.6677 km/hr to stay beneath the airplane
Explanation:
The given parameters are;
The velocity of the airplane, v = 105 km/hr
The direction of the airplane, θ = 25 degrees to the ground = 25°
Therefore, we have that the horizontal component of the velocity of the plane, vₓ is given as follows;
vₓ = v × cos(θ) = 105 km/hr × cos(25) ≈ 98.6677 km/hr
The vertical component of the velocity of the plane, [tex]v_y[/tex], is given as follows;
[tex]v_y[/tex] = v × sin(θ) = 105 km/hr × sin(25) ≈ 44.37 km/hr
The truck only has to travel at a speed equal to the horizontal velocity of the airplane to stay beneath the airplane
Therefore, the travelling speed the truck must be vₓ which is 98.6677 km/hr to stay beneath the airplane.
Combined gas law, A gas balloon has a volume of 106L when the temperature is 318K and the pressure is 1.5 atm. What will its volume be at 293 K and 2 atm.
P1 x v1/t1 = p2 x v2 / t2
use the given values:
1.5 x 106 / 318 = 2 x v2 / 293
Simplify:
0.5 = (2 x v2)/293
Multiply both sides by 293:
146.5 = 2 x v2
Divide both sides by 2:
V2 = 73.25 L
Answer: 73.25 L

Small rocky bodies that are thought to be leftover remnants from the formation of the solar system are called __________. Which term best completes the sentence
An asteroid is a type of space rock, much smaller than a planet, and moves in an elliptical orbit around the Sun.
What are asteroids?It is a smaller body that is part of the solar system and has a diameter of less than 1,000 kilometers.
Asteroids are the subject of constant study due to the proximity they maintain to Earth, despite the fact that the chances of their impacting are very low despite the fact that they have reached the planet in a very remote past.
Therefore, we can conclude that asteroids are characterized by having a very weak gravitational force, they are celestial bodies that orbit around the Sun, and that they are remnants of the matter that gave rise to the Solar System.

a rocket accelerates upwards from rest to a speed of 12km/s in 8 seconds calculate the acceleration
Answer: 1.5 km/s²
Explanation:
Given that,
Initial speed Vi = 0 km/s
Final speed Vf = 12km/s
Acceleration A = ?
Time taken T = 8 seconds
Recall that acceleration is the rate of change of velocity per unit time
i.e acceleration = (Vf - Vi)/T
A = (12km/s - 0km/s) / 8 seconds
A = 12km/s / 8 seconds
A = 1.5 km/s²
Thus, the acceleration of the rocket is 1.5 km/s²

Air always moves from an area of high pressure to an area of ____________ pressure.
Answer:
low
Explanation:
This is because the energy in the air molecules in a high pressured area will constantly move and expand outwards. This is why gas leaks outside of labs, pipes, and soda bottles.
What is the purpose of the cytoplasm
Answer:
:)
Explanation:
The cytoplasm provides a medium for the organelles to remain suspended. The cytoplasm acts as a buffer and protects the genetic material of the cell and also the cellular organelles from damage caused due to movement and collision with other cells. Cellular respiration begins in the cytoplasm with glycolysis
Contrary to popular belief, a ski jumper does not achieve a large amount of "air" when doing a jump (less than 6 feet). This is because the ramp is almost horizontal while the landing is a steep hill. If a ski jumper leaves the hill at 26 m/s in the horizontal direction then travels 240 meters down the slope, what was the vertical distance (dy) that the ski jumper fell?
Answer:
The vertical distance that the ski jumper fell is 417.45 m.
Explanation:
Given;
initial horizontal velocity of the jumper, [tex]V_x[/tex] = 26 m/s
horizontal distance of the jumper, dx = 240 m
The time of the motion is given by;
dx = Vₓt
t = dx / Vₓ
t = 240 / 26
t = 9.23 s
The vertical distance traveled by the diver is given by;
[tex]d_y = V_yt + \frac{1}{2}gt^2[/tex]
initial vertical velocity, [tex]V_y[/tex], = 0
[tex]d_y = \frac{1}{2}gt^2\\\\d_y = \frac{1}{2}(9.8)(9.23)^2\\\\d_y = 417.45 \ m[/tex]
Therefore, the vertical distance that the ski jumper fell is 417.45 m.
A boat travels with a velocity equal to 14.0 meters per second, east in 6.15 seconds. What distance in meters does the boat travel?
Answer:
Distance, d is 86.1 meters.
Explanation:
Given the following data;
Time, t = 6.15secs
Velocity = 14m/s
Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.
Mathematically, velocity is given by the equation;
[tex]Velocity = \frac{distance}{time}[/tex]
[tex]V = \frac{d}{t}[/tex]
[tex]d = Vt[/tex]
Substituting into the above equation;
[tex]d = 14 * 6.15[/tex]
d = 86.1m
Hence, the distance traveled by the boat is 86.1 meters.

A). 2.8 m/s²
В.) 9.8 m/s²
C.) 34 m/s²
D.) 68 m/s²
Answer:
g ≈ 2.82 m/s^2

What is the pattern for mass, speed, and energy.
Please answer this asap.
thanks.
Answer:
The kinetic energy of a moving object is directly proportional to its mass and directly proportional to the square of its velocity. This means that an object with twice the mass and equal speed will have twice the kinetic energy while an object with equal mass and twice the speed will have quadruple the kinetic energy.

A torch has 150J of energy supplied from a battery,
70J are transferred to light, 80J goes to heat, what is
the efficiency of the torch?
The efficiency of the torch light from the total energy supplied and useful energy is 46.7%.
Efficiency of the torch
The efficiency of the torch is the amount of energy used to produce light compared to the total energy supplied to the torch light. This can also be called useful energy.
Total energy supplied to the torch = 150 J
Total energy used to produce light = 70 J
The efficiency of the torch light is calculated as follows;
Efficiency = 70/150 x 100%
Efficiency = 46.7%
Thus, the efficiency of the torch light from the total energy supplied and useful energy is 46.7%.
