A falcon is diving at a speed of 30m/s. It accelerates at a rate of 40m/sand reaches a speed of
100m/s. Calculate the distance it travels during its acceleration.
Answer:
Reasd through the explanartion first :)
Explanation:
Initial velocity, u = 30 m/s
Final velocity, v = 100 m/s
Acceleration, a = 40 m/s²
Distance traveled, s = ?
According to the 3rd equation of motion,
We know that,
v² - u² = 2as
So, putting all the values, we get
⇒ v² - u² = 2as
⇒ (100)² - (30)² = 2 × 40 × s
⇒ 10000 - 900 = 80s
⇒ 9100 = 80s
⇒ 9100/80 = s
⇒ s = 113.75 m.

Why is the unit of momentum called derived unit
Answer:
the SI unit of momentum is :- kg.ms-1
and we know that,
kinetic energy = 1/2 mv2
E=p2/2m
p=(2Em)1/2
so the derived units are (J.kg)1/2
Explanation:
What type of energy comes from the motion of tiny particles of matter?
Answer: Heat
Explanation: All matter is made of tiny particles called atoms, molecules and ions. These tiny particles are always in motion – either bumping into each other or vibrating back and forth. It is the motion of particles that creates a form of energy called heat (or thermal) energy that is present in all matter

Typically, people think of a lava flow when they think of volcanoes. However, some eruptions are mostly ash and steam released into the atmosphere. This type of volcanic eruption is blamed for causing what is referred to as a "Little Ice Age" starting in the 13th century. The ash and steam blocked the sun's rays causing extreme cold and agricultural difficulty which lead to massive decreases in populations.

What is one characteristic of the convection inside the sun?
- Cells of circulating gasses called granules
- Thick clouds of dust and gasses
- Large cells of rising and sinking gasses
- Nuclear reactions between hydrogen atoms
Answer: 3- Large cells of rising and sinking gasses
Explanation: Hotter gas coming from the radiative zone expands and rises through the convective zone. It can do this because the convective zone is cooler than the radiative zone and therefore less dense. As the gas rises, it cools and begins to sink again. As it falls down to the top of the radiative zone, it heats up and starts to rise. This process repeats, creating convection currents and the visual effect of boiling on the Sun's surface.

Answer:
Is it a test
Explanation:
a car on a circular track accelerates from rest. the radius of the track is 0.30km and the magnitude of the constant angular acceleration is 4.5x10-3 rads/s squared. find the centripetal acceleration of the car when it has completed half of a lap.
Answer:
The centripetal acceleration of the car is 50.4 m/s²
Explanation:
Given;
radius of the track, r = 0.3km = 300 m
constant angular acceleration, α = 4.5 x 10⁻³ rad/s²
during half of a lap, θ = π
Determine time of motion
θ = ωt + ¹/₂αt²
π = 0 + ¹/₂αt²
t² = 2π / α
t² = ( 2 x 3.142) / (4.5 x 10⁻³)
t² = 1396.44
t = √1396.44
t = 37.369 s
Determine the angular velocity
[tex]\omega_f = \omega_i + \alpha t\\\\\omega_f = 0 \ + \ 37.369*4.5*10^{-3}\\\\\omega_f = 0.168 \ rad/s[/tex]
Determine the centripetal acceleration of the car
[tex]\alpha _c = \omega^2 r\\\\\alpha _c = 0.168*300\\\\\alpha _c =50.4 \ m/s^2[/tex]
Therefore, the centripetal acceleration of the car is 50.4 m/s²

which of the following is not non constant force
A. gravitational force
B. frictional force
C.magnetic force
D. electrical force
Answer:
Frictional force. hope this helps have a good day
Answer:
frictional force
Explanation:
Friction always acts to oppose any relative motion between surfaces. For the simple example of a book resting on a flat table, the frictional force is zero. There is no force trying to move the book across the table, so there is no need for a frictional force because there is nothing for the frictional force to oppose.

1 Newton in Earth gravity is the equivalent weight of 1/9.80665 kg on Earth. This is derived using Newton's second law f=ma and assuming Earth gravity of 9.80665 m/s2. 1 N (Earth) = 0.101971621297793 kg.
Chanel has some cotton candy that came in a cloudy shape. She wants to make it more dense. Which describes the candy before and after Chanel manipulated it? The candy before was a cube, and the candy after was a ball. The candy before was compacted, and the candy after was fluffy. The candy before was fluffy, and the candy after was compacted. The candy before was a ball, and the candy after was a cube.
Answer:
The candy before was fluffy, and the candy after was compacted.
Explanation:
By definition, something that is fluffy is something very soft, and when you talk about fluffy food (e.g. cakes, cotton candy) it is food that has a lot of air in it. In this case, the cotton candy originally had the shape of a cloud and was not dense, therefore, it was fluffy.
Something that is compact, it something that is dense, solid and generally small. Since Chanel wanted her cotton candy to be more dense, she compacted it .
Answer:
c
Explanation:
As the cloud passes over the building, a lightning strike occurs and a charge of 0.84C flows through the lightning conductor. The charge flows for 3.5 × 10^-5 s.
Calculate the average current in the lightning conductor during this time. State the formula used in your answer
Answer:
I=24,000 Amp
Explanation:
Electric Current
Is a measure of the quantity of charge Q flowing by a point in a time period of t.
The standard metric unit for the current is the Ampere, often abbreviated as Amps or A.
It can be calculated as:
[tex]\displaystyle I=\frac{Q}{t}[/tex]
The cloud generates a lightning strike that releases a charge Q=0.84 C during a time [tex]t=3.5\cdot 10^{-5}\ sec[/tex].
The current is of course, not of a constant value, but an average value can be calculated by using the above formula:
[tex]\displaystyle I=\frac{0.84}{3.5\cdot 10^{-5}}[/tex]
[tex]\boxed{I=24,000\ Amp}[/tex]
