how long would it take to get to the moon going around 75 miles an hour

Answers

Answer 1
The moon is our only known natural satellite, which means it's the only natural object that orbits Earth. At its closest, it is 223,700 miles away from Earth. So if you were riding in a car going 70 miles per hour, it would take you 135 days to get there.

Answers

Answer:

3600 m SOUTH

Explanation:

avg velocity= (change displacement)/(change in time)

2.0 m/s= x/ (1800 s)

displacement= (2.0 m/s * 1800s)= 3600 m SOUTH

A man runs at 7.5 m s-1 due east across the deck of a ship which moves at 10.0 m s-1 due north. Determine the resultant velocity of the man( his velocity relative to the water)

Answers

Answer:

12.5 m/s North/east

Explanation:

I thought of it as a graph. I basically just found the distance between the points (0,0) and (10, 7.5)!

The resultant velocity of the man is 12.5 m/s.

What is velocity?

The rate at which a body's displacement changes in relation to time is known as its velocity. Velocity is a vector quantity with both magnitude and direction. SI unit of velocity is meter/second.

Velocity of the man: v₁ = 7.5 m/s (due east )

Velocity of the ship: v₂ = 10 m/s. ( due north.)

Hence, the man and the ship move in perpendicular direction.

So,  his velocity relative to the water = the resultant velocity of the man

= √(7.5² + 10²) m/s = 12.5 m/s.

Hence, resultant velocity of the man is 12.5 m/s.

A mass is dropped from a height h above the ground, and freely falls under the influence of gravity. Which graphs here correctly describes the displacement and velocity of the object during the time the object is falling? Consider the "up" direction to be positive.

Which graph is it?​

Answers

Answer:

B

Explanation:

The only force acting on the block is gravity, so the block has a constant, negative acceleration. This means the velocity of the block is decreasing at a constant rate, so the answer is B, D, or E. Velocity is the rate of change of displacement, and answer choice B is the only one that has a displacement graph that matches that idea.

Answer: Graph B here correctly describes the displacement and velocity of the object during the time the object is falling. Option B is correct.

It is given that the mass of an object is dropped from height 'h' above the ground and "up" direction is taken to be positive.

It is required to find the graph which describes the displacement and velocity of the object during the time the object is falling.

Which graphs here correctly describes the displacement and velocity of the object during the time the object is falling?

If any body falls freely towards the ground, then its acceleration is decreasing constantly with respect to time. That means velocity of an object will also be decreased as shown in graph B. Also we know that velocity is the rate of change of displacement.

As it is given in question that up direction is positive then it is also considered that downward be negative means decreasing.

Therefore, both the quantities are decreasing. So graph B correctly describes the displacement and velocity of the object during the time the object is falling.

How can you find the frequency or period of ocean waves?

Answers

Answer:    As you probably have seen in the ocean or a lake, the stronger the wind, the higher the waves. The period and wavelength can be expressed in terms of their reciprocals, the wave frequency ω = 2(pi)/T, and the wave number κ = 2(pi)/λ.

Explanation:     To find the period, we solve for T=1f, given the value of the frequency (f=2s−1). T=12 s−1=0. 5 s. Since one definition of wavelength is the distance a wave has traveled after one complete cycle (or one period), the values for the wavelength (λ=0.9m) as well as the frequency are given.

a sled with no initial velocity accelerates at a rate of 3.2 m/s squared down a hill how long does it take to sled to go 15 m to the bottom ​

Answers

Answer:

After 3.06seconds

Explanation:

Given that the following data are

acceleration a= 3,2m/s^2

distance s=15m,

time t=?  

Applying the formula for the equation of motion we have

s=ut+1/2at^2

we no initial velocity (u=0)

substituting our given values into the expression we have

15=0*t+1/2(3.2)t^2

15=1/2(3.2)t^2

15=3.2t^2/2

30=3.2t^2

t^2=30/3.2

t^2=9.375

Squaring both sides we have

t=√9.375

t=3.06seconds

It will take the sled 3.06 seconds to get to the bottom

ATP and NADPH is created from light dependent then transfered and transformed into different components from the calvin cycle (light independent cycle)

Two compounds are produced during the light-dependent reaction then used in the light-independent reaction - A) ATP and NADPH

Photosynthesis is a process that takes place in the Chloroplast of plant cells. Autotrophs obtain their energy source (food) in the presence of sunlight.

The photosynthesis process occurs in two distinct stages; light-dependent reaction and light-independent reactions.

the light reactions take place in the thylakoid membranes of chloroplasts.The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesisThese molecules are the energy storage molecule ATP and the reduced electron carrier NADPH.

Thus, two compounds are produced during the light-dependent reaction then used in the light-independent reaction - A) ATP and NADPH

L= 6.3 km from the finish line, a bird begins

flying straight from the runner to the finish

line at vb= 42 km/hr (5 times as fast as the

runner). When the bird reaches the finish

line, it turns around and flies directly back to

the runner.

Answers

Answer:

Total distance traveled by bird is 10.5 km.

Explanation:

Given that,

Velocity of runner= 8.4 km/hr

Distance = 6.3 km

Velocity of bird = 42 km/hr

Suppose, How far does the bird travel?

We need to calculate the time of bird

Using formula of time

[tex]t=\dfrac{d}{v_{b}}[/tex]

Put the value into the formula

[tex]t=\dfrac{6.3}{42}[/tex]

[tex]t=0.15\ hr[/tex]

We need to calculate the distance runner travels during time period

Using formula of distance

[tex]d=v_{r}\times t[/tex]

[tex]d=8.4\times0.15[/tex]

[tex]d=1.26\ km[/tex]

We need to calculate the distance of runner to FL

Using distance

[tex]d'=6.3-1.26[/tex]

[tex]d'=5.04\ km[/tex]

We need to calculate the net closing speed between runner and bird

Using speed

[tex]v'=v_{r}+v_{b}[/tex]

[tex]v'=8.4+42[/tex]

[tex]v'=50.4\ km/hr[/tex]

We need to calculate the time for runner and bird to meet

Using formula of time

[tex]t=\dfrac{d}{v'}[/tex]

Put the value into the formula

[tex]t=\dfrac{5.04}{50.4}[/tex]

[tex]t=0.1\ hr[/tex]

We need to calculate the distance covered by runner

Using formula of distance

[tex]d=vt[/tex]

Put the value into the formula

[tex]d=8.4\times0.1[/tex]

[tex]d=0.84\ km[/tex]

We need to calculate the distance covered by bird to runner

Using formula of distance

[tex]d=vt[/tex]

Put the value into the formula

[tex]d=42\times0.1[/tex]

[tex]d=4.2\ km[/tex]

We need to calculate the total distance

Using distance

[tex]D=6.3+4.2[/tex]

[tex]D=10.5\ km[/tex]  

Hence, Total distance traveled by bird is 10.5 km.
