What is the velocity (in metres per second) of a Canadian
Forces CF-18 fighter jet that travels 8.864 km [S] in
0.297 min?
Answer:
497 m/s
Explanation:
(8.864 x 10^3 m)/(0.297 * 60 sec) = 497 m/s
The velocity (in metres per second) of a Canadian Forces CF-18 fighter jet would be 497.41 meters/second.
What is speed?The total distance covered by any object per unit of time is known as speed.
As given in the problem we have to find out the velocity (in meters per second) of a Canadian Forces CF-18 fighter jet that travels 8.864 kilometers [S] in 0.297 minutes,
The distance traveled by the CF-18 fighter jet = 8.864 kilometers
1 kilometer = 1000 meters
8.864 kilometers = 8.864× 1000 meters
=8864 meters
The time taken by CF-18 fighter jet = 0.297 minutes
1 minute = 60 seconds
0.297 minutes = 0.297 ×60 seconds
=17.82 seconds
The velocity of the CF-18 fighter jet =8864 meters/17.82 seconds
= 497.41 meters/second

A heat engine is used to convert heat into which of the following?
Answer:
work
Explanation:
A ball is thrown 125 meters upward and then falls the same distance back to Earth. Neglecting air resistance, its total time in the air is
Answer:
the ball is in the air for 10 seconds
Explanation:
let gravity = 10m/s/s
height = 1/2 acceleration • time^2
125 m = 1/2 • 10 m/s/s • time ^2
125m = 5 m/s/s • time^2
25s = time^2
5 s = time
5 seconds is the time required for half of the flight
time total = 2 • time
time total = 2 • 5s
time total = 10 s

A car of mass 1000 kg is heading east at 25 m/s. It collides with a car of mass 1200 kg heading north at 30 m/s. When the cars collide, they stick together.
d. At what angle do the cars move after the collision? (2 points)
Given :-
A car of mass 1000 kg is heading east at 25 m/s. It collides with a car of mass 1200 kg heading north at 30 m/s. When the cars collide, they stick together.To Find :-
At what angle do the cars move after the collision?Solution :-
Here it's given that a car of mass 1000kg moving with velocity of 25m/s North . Another car of mass 1200kg is moving with velocity 30m/s East.
So that ,
[tex]v_{1}= 25m/s \ E= 25 \hat{i} m/s [/tex]
And ,
[tex]v_{2}= 30m/s \ N = 30 \hat{j} m/s [/tex]
See attachment .
From Triangle law of vector addition , the resultant of both vectors will be given by third side of the triangle taken in opposite direction.
So , if the resultant velocity makes an angle [tex]\theta[/tex] . Then ,
[tex] tan\theta = \dfrac{v_2}{v_1} [/tex]
Substituting the respective values,
[tex]tan\theta =\dfrac{30m/s}{25m/s} [/tex]
Simplify ,
[tex]tan\theta =\dfrac{6}{5}[/tex]
Take arctan both sides ,
[tex]\theta = tan^{-1}\bigg(\dfrac{6}{5}\bigg)[/tex]
Hence the cars move at an angle of tan-¹(6/5) NE after the collision .

A5 kg body is having a Kinetic energy of 250 J. What is the velocity of the body?
15 m/s
20 m/s
40 m/s
10 m/s
ME
Answer:
10 m/s
Explanation:
KE = 1/2 • m • v^2
250 J = 1/2 • 5 kg • v^2
(2 • 250 J / 5 kg )^1/2 = v
(100)^1/2 = v
10 = v
One day, the distance between the crests of the waves at sea is 2.5m. The shortest time between the lowest and highest positions of the floating boat was 0.625 seconds.
a) Calculate the wave period.
b) Calculate the speed of the wave.
Answer:
1.25 sec, 2 m/s
Explanation:
Period = 2 * 0.625 sec = 1.25 sec
speed = 2.5/1.25 = 2 m/s
In a pulley system, two blocks are connected by a rope as shown below. The coefficient of static friction between block A and the surface is 0.8. Block A has a mass of 20kg. What is the minimum mass that block B can have so that block A moves?
Hi there!
We can begin by doing a summation of forces for each block.
Block A:
This block has the force of tension (in direction of acceleration +) and static friction (opposite direction -) acting on it. Thus:
[tex]\Sigma F_A = T - F_s\\\\m_Aa = T - \mu m_Ag[/tex]
Block B:
This block has the force of tension (opposite of acc. -) and gravity (in direction of acc +), working on it.
[tex]\Sigma F_B = m_Bg - T\\\\ m_Ba = m_Bg - T[/tex]
Add both of the expressions and solve for the maximum mass of Block B.
[tex]\Sigma F = m_Bg - T + T - \mu m_Ag\\\\a(m_A + m_B) = m_Bg - \mu m_Ag[/tex]
To find the minimum value, we can set a = 0, so:
[tex]0 = m_Bg - \mu m_Ag\\\\\mu m_Ag = m_B g\\\\0.8(20)(9.8) = m_B (9.8)\\\\m_B = \frac{0.8(20)(9.8)}{9.8)} = \boxed{16 kg}[/tex]
The block must weigh > 16 kg for block A to move.

A copper wire has a diameter of 1.947 mm. What magnitude current flows when the drift velocity is 1.79 mm/s
Answer:
72.5 A
Explanation:
There are about 13.6 coulombs of free electron charges in each cubic mm of copper. So, the rate of movement of charge is that quantity multiplied by the volume in the flow.
V = πr²h . . . . . volume of a cylinder
V = π(1.947 mm/2)²(1.79 mm/s) = 5.329 mm³/s
Then the charge flow rate is ...
(13.6 C/mm³)(5.329 mm³/s) = 72.5 C/s
The magnitude of the current is about 72.5 amperes.
______
Additional comment
The volume of free charge in copper can be computed from the density, molar mass, number of atoms in a mole, number of charges in a coulomb, and the number of free charges per atom. Some of the combinations of necessary calculations can be found with a web search, so it is not unreasonable to presume that the charge density is known.

Please Mark Me As a brainliestIs black made of all colors?
Black is not a color, but rather a shade. In color theory, a shade is a pure color mixed with black. It decreases its lightness while nearly conserving its chromaticity. Strictly speaking, a "shade of black" is always a pure black itself and a "tint of black" would be a neutral gray. Unlike these, many off-black colors possess a hue and a colorfulness (also called saturation).
Attached is an image showing a few of the different shades of black.
Hope this helps! Brainliest would be much appreciated! Have a great day! :)
The answer is "no" because black is not made of all colors, in fact black is not a color, but black is the absence of light.
What is Light?Light is an electromagnetic radiation which can be recognized by the human eye. Electromagnetic radiation occurs at a wide variety of wavelengths, from cosmic rays with wavelengths smaller than around 1 1011 meters to radio waves estimated in meters.
Within that large spectrum, the colors visible to humans comprise a relatively small band, ranging from around 700 nanometers for red light to roughly 400 nm for violet light. The spectral areas close to the visible band are also referred to as light, with infrared at one side and ultraviolet the other.
The absence or full assimilation of visible light produces the color black. It is an anamorphic lens color with no tint, similar to white and gray. It is frequently used symbolically or colloquially to denote darkness.

What is the Story of Issac Newton
Answer:
Isaac Newton is considered one of the most important scientists in history. ... During his lifetime Newton developed the theory of gravity, the laws of motion (which became the basis for physics), a new type of mathematics called calculus. The legend is that Newton discovered Gravity when he saw a falling apple while thinking about the forces of nature. Whatever really happened, Newton realized that some force must be acting on falling objects like apples because otherwise they would not start moving from rest.

A bullet is shot vertically upward with an initial velocity of 128 ft/s. The bullet's height after t seconds is y(t) = 128t - 16t2. What is the height of the bullet at the time the velocity is 0 ft/s?
The height of the bullet when the velocity is zero is 256 ft.
Height of the bullet when the velocity is zeroThe height of the bullet when the velocity is zero is determined by taking derivative of the function as shown below;
[tex]v = \frac{dy}{dt} = 128 -32t \\\\when \ v \ is \ zero\\\\v = 0\\\\128 - 32t = 0\\\\32t = 128\\\\t = \frac{128}{32} \\\\t = 4 \ s[/tex]
The height of the bullet at this time is calculated as follows;
