Answer:
answer is an ASTEROID
Explanation:
Iridium is a material that forms at very high temperatures, which is why its presence shows that in the impact zone the temperature rose a lot, so we can imagine that the impact was by a body traveling at high speed, which is consistent with a body that comes from space.
An asteroid is a celestial body of some size that when entering the atmosphere heats up and collides with the Earth, leaving a crater that in general is much larger than the diameter of the object.
A meteorite is a small fraction of an asteroid that has been separated by the pressure of the sun, the attraction of the Earth, Moon or another massive body or a combination of these effects, in general, meteorites are small and when they enter the atmosphere They are consumed by heat and very few reach the surface of the Earth, those that do reach are very small.
Therefore due to the size of the crater and the existence of many dead animals around the body must have been very heavy, so the correct answer is an ASTEROID

Describe the movement of the Moon.
Someone please help with this one and the other I posted, I have two hours till it’s due :(
Answer:
The Moon spins in space in a movement called rotation. Oddly enough, it also takes the Moon about 27 days to spin around once (which is much slower than Earth's rotation, which only takes 24 hours). That means the Moon goes all the way around Earth in the same amount of time it takes to spin around just once!

1. Your car's engine suddenly dies as you're driving 35m/s down the highway. If the sum of friction forces on your car is 7000N and your car weighs 1300kg at what rate will you accelerate to a stop? |
Answer:
Explanation:
Frictional force = 7000 N
mass of car = 1300 kg . Initially car was moving uniformly so no force acting on car at that time . After frictional force acts , it creates deceleration or negative acceleration .
acceleration = force / mass
= - 7000 / 1300
= - 5.38 m / s²

1.which type of image is right side up but left and right are reversed
A.real
B.virtual
2.Real images are:
A.always inverted
B.magnified or diminished
C.can be obtained on screen
D.all the above
Answer:
see below
Explanation:
1) B, virtual because the when you stand in front of a mirror, the image formed is virtual and Image is laterally inverted
2) D because, when using converging lens , real image is formed, it is inverted and it can also be magnified or diminished when the object is placed at different focal length.
real image can be captured on the screen because light rays meet at the image position
when using converging lens, the image formed if it is virtual is upright.

A reference point allows you to determine the _____________of an object state state speed speed position position dimension
Answer:
Position.
Explanation:
Motion can be defined as a change in the location (position) of a physical object or body with respect to a reference point.
This ultimately implies that, motion would occur as a result of a change in location (position) of an object with respect to a reference point or frame of reference i.e where it was standing before the effect of an external force.
Mathematically, the motion of an object is described in terms of acceleration, time, distance, speed, velocity, displacement, position, etc.
A reference point refers to a location or physical object from which the motion (movement) of another physical object or body can be determined.
For example, a point on a map is considered to be a reference point because it represents the starting point of an object or person in motion.
Hence, a reference point allows you to determine the position an object.

2. An upward force is applied to lift a 15 kg box to a height of 5 m at a constant speed. How
nlich work is done on the box?
500 J
65 J
150 J
735 J
Can you please help me
Answer:
D) 735 J(oules)
Explanation:
Work is defined as force * distance
Force is defined as mass * acceleration
Given a mass of 15 kg and a gravitational acceleration of 9.8 m/s² since the box is being lifted up, the force being applied to the box is 15 kg * 9.8 m/s² = 147 N
Since the distance is 5 meters, the work done is 147 N * 5 m = 735 N/m = 735 J, making D the correct answer.
a car is traveling 20 m/s. it takes 4 seconds with a 7,500 n force to come to a stop. what is the mass of the car
Answer:
mass equals 375 kg
Explanation:
f=ma
f=7500
a=20
m=f/a
m=7500/20
m=375
1500 kg is the mass of the car.
What is Newton's second law of motion?Newton's second law of motion describes the relationship between an object's mass and the amount of force needed to accelerate it.
Newton's second law is often stated as,
F=ma, which means the force (F) acting on an object is equal to the mass (m) of an object times its acceleration (a).
According to the question,
Mass = 20m/s , Time = 4s , Force = 7500 N
a = Δv/Δt
a = 20m/s / 4s
a = 5 m/s²
If F = ma then,
7500 N = m x 5 m/s²
m = [tex]\frac{7500 N }{ 5m/s^{2} }[/tex]
m = 1500 kg
Therefore,
1500 kg is the mass of the car.

Explanation:
A vector has components A x = 7.6 m and A y = 15.9 m. What is the angle (in degrees that vector makes with the x-axis?
Answer:
θ = 64.5º
Explanation:
To find the angles of a vector with respect to some axis of a coordinate system, the tangent function is used.
tan θ = [tex]\frac{y}{x}[/tex]
where y is the opposite leg and x is the adjacent leg
in this case the angle is
θ = tan⁻¹ [tex]\frac{A_y}{A_x}[/tex]
let's calculate
θ = tan⁻¹ [tex]\frac{15.9}{ 7.6}[/tex]
θ = tan⁻¹ 2.09
θ = 64.5º
this angle is with respect to the positive pâté of the x axis

what is the electric potential difference of 5cm from a point charge of -2.0µc
Answer:
V = 360 kV
Explanation:
Given that,
Charge, q = -2µC
We need to find the electric potential difference of 5cm from a point charge.
We know that the formula for the electric potential is given by :
[tex]V=\dfrac{kq}{r}\\\\V=\dfrac{9\times 10^9\times 2\times 10^{-6}}{0.05}\\\\V=360000\ V[/tex]
or
[tex]V=360\ kV[/tex]
So, the electric potential difference is 360 kV.

As the amplitude of a mechanical wave increases, which of the following quantities
increases?
A.wavelength
B.frequency
C.energy
D.speed
.c ...energy
Explanation:
Amplitude does not affect wavelength. It also does not affect wave speed. Amplitude is the energy of the wave measured from the rest position to the top of the crest. A wave with more energy has a higher up crest/ higher amplitude.
As the amplitude of a mechanical wave increases, the quantity which increases is: C. energy.
What is a mechanical wave?A mechanical wave can be defined as a type of wave that requires a medium for its propagation and it creates a disturbance in the medium. Thus, a good example of mechanical wave is sound wave, which is typically transported in a perpendicular direction.
