Answer:

Because of earth's tilt

Explanation:

Answer:

Different parts of Earth's surface receive different amounts of sunlight. ... Because of the Earth's tilt the sun's rays strike the surface at a slant at the poles; they are less focused. This spreads the rays over a wide area. Because the sun's rays hit at a slant, the area is heated less.

Answer:

200/67.1224321241 = 2.97962981482 hours to travel 200 miles.

Hope this helps :)

Explanation:

First, convert the speed of the bus back to km/h so it makes things easier. The bus is going at an unreasonably high seed of 108 km/h and will usually result in a crash caused by the driver being unable to control the bus at such high speeds, even it won’t topple over at an inclination of 28 degrees for double decker buses (when the bus is stationary. If the prototypes can’t meet this requirement, the prototype fails the safety test and won’t be used as a bus for carrying passengers).

If you ignore that problem, we will start to do the calculation. 108 km/h is equal to 67.1224321241 mph, so it would take 200/67.1224321241 = 2.97962981482 hours to travel 200 miles.

2.97962981482 hours is equal to 2 hours, 58 minutes, 46 seconds, 667 milliseconds, 333 microseconds and 352 nanoseconds.

Here is the list of descending order of time magnitude of smaller than one second for extra information.

Decisecond = 0.1 second (one tenth)

Centisecond = 0.01 second (one hundredth)

Millisecond = 0.001 second (one thousandth)

Microsecond = 0.000001 second (one millionth)

Nanosecond = 0.000000001 second (one billionth)

Picosecond = 0.000000000001 second (one trillionth)

Femtosecond = 0.000000000000001 second (one quadrillionth)

Attosecond = 0.000000000000000001 second (one quintillionth)

Zeptosecond = 0.000000000000000000001 second (one sextillionth)

Yoctosecond = 0.000000000000000000000001 second (one septillionth)

Planck time = 0.00000000000000000000000000000000000000000001 second

Planck time is the smallest measurable time interval in theory.

Answer:

Explanation:

Answer:

2 m/s^2, west

Explanation:

Vf=final velcoity

Vi=initial velocity

t=timw

[tex]a = \frac{vf - vi}{t} [/tex]

=

[tex] \frac{15 - 25}{5} [/tex]

= - 2 m/s^2

The - changes direction and makes it opposite

2 m/s, west

The magnitude of the object acceleration is -2m/s². Since the acceleration of the object is negative, hence the direction will be towards the west

Acceleration is the change in velocity of a body with respect to time. Mathematically;

[tex]a=\frac{v-u}{t}[/tex]

v is the final velocity

u is the initial velocity

t is the time taken;

Given the following parameters

v = 15m/s

u = 25m/s

t = 5.0secs

Substitute the given parameters into the formula to have:

[tex]a=\frac{15-25}{5}\\a=\frac{-10}{5}\\a=-2m/s^2[/tex]

Hence the magnitude of the object acceleration is -2m/s². Since the acceleration of the object is negative, hence the direction will be towards the west.

Answer:

The cyclist takes 10 seconds to accelerate to 12 m/s.

Explanation:

Constant Acceleration Motion

It's a type of motion in which the velocity of an object changes by an equal amount in every equal period of time.

Being a the constant acceleration, vo the initial speed, vf the final speed, and t the time, the following relation applies:

[tex]v_f=v_o+at[/tex]

Solving for t:

[tex]\displaystyle t=\frac{v_f-v_o}{a}[/tex]

The cyclist starts from rest (vo=0) and moves at vf=12 m/s with an acceleration [tex]a=1.2\ m/s^2[/tex].

Calculate the time:

[tex]\displaystyle t=\frac{12-0}{1.2}[/tex]

[tex]\displaystyle t=\frac{12}{1.2}[/tex]

[tex]\boxed{t=10\ sec}[/tex]

The cyclist takes 10 seconds to accelerate to 12 m/s.

Explanation:

Omnicalculator

Given the force exerted on the object with the given mass, the acceleration of the object is 5m/s².

Given the data in the question;

Acceleration; [tex]a =\ ?[/tex]

To determine the acceleration of the mass, we use Newton Second Law of Motion:

[tex]F = m * a[/tex]

Where m is mass of the object and a is the acceleration.

We substitute our given values into the equation and solve for "a"

[tex]10.0N = 2.0kg * a\\\\10.0kg.m/s^2 = 2.0kg * a\\\\a = \frac{ 10.0kg.m/s^2}{2.0kg}\\\\a = 5m/s^2[/tex]

Therefore, given the force exerted on the object with the given mass, the acceleration of the object is 5m/s².

Answer:

✔️Car A and Car B are moving in opposite directions.

✔️Car A is moving faster than Car B.

✔️Car A started ahead of car B.

Explanation:

The position-time graph shows Car A and Car B. The graph reveals that both cars are moving in opposite directions.

Car A shows a positive slope and Car B shows a negative slope.

The graph also shows that Car A started ahead of Car B. It's seen from the graph that Car A started from the origin.

Therefore, we conclude that the correct statements are:

✔️Car A and Car B are moving in opposite directions.

✔️Car A is moving faster than Car B.

✔️Car A started ahead of car B.

Answer:

The first person to "measure gravity" is sir Issac newton

Answer:

a. 10 hours

b. Approximately 4.03 km/h to shore

Explanation:

The width of the English Channel at the narrowest point = 35 km

The speed of the current across the English Channel across the narrowest point = 2 km/h

a. The relative velocity of the swimmer north to south = 3 km/h

Therefore, the the time it would take the swimmer to swim north to south will be given as follows;

Time = Distance/Velocity = 35 km/(3.5 km/h)  =10 hours

The time it would take = 10 hours

It would take 10 hours for her to cross the 35 km distance

b. Given that she has a relative velocity of 3 km/h north to south, we have;

The magnitude of her relative velocity to shore = √((Her relative velocity north to south)² + (The velocity of the English Channel east to west)²)

∴ The magnitude of her relative velocity to shore = √(3.5² + 2²) = (√65)/2 km/h

The magnitude of her relative velocity to shore ≈ 4.03 km/h
