when talking about Acceleration ,what is significant about the about the sign(+ or -)?
Answer:
Acceleration at its most basic is the act of increasing your running speed. From a standing start (or blocks), you explode into action. If you’re already running, you pick up the pace. Acceleration continues until you can no longer increase your speed, at which point you achieve maximum velocity (top-end speed). Acceleration seems simple enough. The plus means your increasing speed, the k=minus means your decreasing in speed.

The acceleration due to gravity is 9.81 m/s2, towards the Earth. Rain falling from an altitude of 9,000 m would fall for about 1.5 minutes before hitting the ground (ignoring air resistance). What would be the final speed of a raindrop by the time it reaches the ground?
Answer:
the final speed of the rain is 541 m/s.
Explanation:
Given;
acceleration due to gravity, g = 9.81 m/s²
height of fall of the rain, h = 9,000 m
time of the rain fall, t = 1.5 minutes = 90 s
Determine the initial velocity of the rain, as follows;
[tex]h = ut + \frac{1}{2} gt^2\\\\9000 = 90u + \frac{1}{2} (9.8)(90)^2\\\\9000 = 90u + 39690\\\\90u = -30690\\\\u = \frac{-30690}{90} \\\\u = -341 \ m/s[/tex]
The final speed of the rain is calculated as;
[tex]v^2 = u^2 + 2gh\\\\v^2 = (-341)^2 + 2(9.8\times 9000)\\\\v^2 = 292681\\\\v = \sqrt{292681} \\\\v = 541 \ m/s[/tex]
Therefore, the final speed of the rain is 541 m/s.
Answer:
The magnitude of the final speed of a raindrop by the time it reaches the ground will be 541.45 m/s.
Explanation:
The final speed of the raindrop can be found using the following equation:
[tex] v_{f} = v_{0} - gt [/tex]
Where:
[tex]v_{f}[/tex]: is the final speed =?
[tex]v_{0}[/tex]: is the initial speed
g: is the acceleration due to gravity = 9.81 m/s²
t: is the time = 1.5 min
First, we need to find the initial speed:
[tex] y_{f} = y_{0} + v_{0}t - \frac{1}{2}gt^{2} [/tex]
Where:
[tex]y_{f}[/tex]: is the final height = 0
[tex]y_{0}[/tex]: is the initial height = 9000 m
Hence, the initial speed is:
[tex] v_{0} = \frac{y_{f} - y_{0} + \frac{1}{2}gt^{2}}{t} = \frac{0 - 9000 m + \frac{1}{2}9.81 m/s^{2}*(90 s)^{2}}{90 s} = 341.45 m/s [/tex]
Hence, the final speed is:
[tex] v_{f} = v_{0} - gt = 341.45 m/s - 9.81 m/s^{2}*90 s = -541.45 m/s [/tex]
Therefore, the magnitude of the final speed of a raindrop by the time it reaches the ground will be 541.45 m/s.

please thank the person above me though, they deserve it.
These snakes can sense electromagnetic waves that have a lower frequency and a longer wavelength.
How do snakes detect?With almost ineffective hearing and vision, snakes can be extremely fast animals. Snakes can use chemoreceptors, heat, and even their tails to recognize prey and mates. With mostly ineffective hearing and vision systems, snakes can be extremely fast animals.
They also “see” in infrared. Thanks to the mechanism, they can track prey up to a meter away by the heat of their bodies. They use a simple organ, the loreal pit, located near the nostrils.

If it is 9 am in San Francisco, is it also 9 am in New York? Why or why not?
If it is 9 am in San Francisco, then there will be 12pm in New York. it happens because of spin rotation of our earth.
What is Clock ?A clock or a timepiece is a device used to measure time. The clock is one of the oldest human inventions. It has three hands moves in the circle. one is second hand, which show seconds. Second hand shows hours and third hand which is smaller than other shows hours.
San Francisco, California is 3 hours behind New York. There will be 12pm in New York when it is 9 am in San Francisco. Day and night happens because of our earth is spinning about itself. when we take a football in the dark room and illuminated it by the torch, then one side of the ball gets illuminated and other side of the ball gets dark due to shadow of its own, Same happens with our earth. it this case torch is our sun and earth is our football. The people who are on the darker side they are in the night and who are in the light side they are in the morning.
Morning starts where edge of the light is. Tme changes with lateral distance on the earth. The points which is on same longitude have same time. There is lateral displacement from San Francisco to New York. Therefore there is time lag between them.
Hence there is time lag.

A roller coaster, traveling with an initial speed of 23 m/s, decelerates
uniformly at -4 m/s2 to a full stop. How far does the roller coaster travel
during its deceleration?
I NEED STEP BY STEP EXPLANATION
Answer:
5 and 3/4 meters
Explanation:
This is because if it is slowing down by 4 meters and it was moving at 23, then you would figure out how many times 4 can go into 23 and you'd get 5 and 3/4 meters.

A construction crane is on top of a skyscraper which has height 45m. The crane itself is 10m in height. What is the gravitational potential energy in joules of a 60kg worker who is standing on top of the crane? (Use g=9.81 in your calculations)
Answer:
32340J
Explanation:
Given parameters
Height of skyscraper = 45m
Height of crane = 10m
Mass of worker = 60kg
g = 9.81m
Unknown:
Gravitational potential energy = ?
Solution:
The gravitational potential energy of a body is the energy due to the position of the body.
It is expressed as:
G.P.E = mgh
m is the mass
g is the acceleration due to gravity
h is the height = 45 + 10 = 55m
G.P.E = 60 x 9.8 x 55 = 32340J
The athlet at point A runs 150m east, then 70m west and then 100 east
Determine the resultant displacement of the athlete relative to point A
Answer:
180m to the east
Explanation:
Displacement is the distance traveled in a specific direction. It is a vector quantity with both magnitude and direction. Therefore, the start and finish position is very paramount.

A car's velocity changes from 40 m/s to 30 m/s in 40 seconds. What is the
acceleration of the car?
Answer:
- 0.25m/s²
Explanation:
Given parameters:
Initial velocity = 40m/s
Final velocity = 30m/s
Time taken = 40s
Unknown:
Acceleration of the car = ?
Solution:
Acceleration is the rate of change of velocity with time.
So;
Acceleration = [tex]\frac{Final velocity - Initial velocity }{time }[/tex]
Acceleration = [tex]\frac{30 - 40}{40}[/tex] = - 0.25m/s²
This implies that the car will decelerate at a rate of 0.25m/s²

A ball rolls with a speed of 3 m/s across a level table that is 1.5m above the floor. How far along the floor is the landing spot from the table?
Answer:
d = 1.65 m
Explanation:
Given that,
The speed of a ball, v = 3 m/s
A ball rolls a level table that is 1.5 m above the floor.
We can find how long the ball is in free fall. We can use the second equation of kinematics as follows :
[tex]s=ut+\dfrac{1}{2}gt^2[/tex]
u is the initial speed in the vertical direction
So,
[tex]s=\dfrac{1}{2}gt^2\\\\t=\sqrt{\dfrac{2s}{g}} \\\\t=\sqrt{\dfrac{2\times 1.5}{9.8}} \\\\t=0.55\ s[/tex]
Now, using the formula of velocity.
[tex]v=\dfrac{d}{t}\\\\d=vt\\\\d=3\times 0.55\\\\d=1.65\ m[/tex]
So, the landing spot is at 1.65 m from the table.
