Answer:

SO ANSWER AGRE AS FOLLOWS:

Explanation:

A. Wind is the movement of air, caused by the uneven heating of the Earth by the sun and the Earth's own rotation. Winds range from light breezes to natural hazards such as hurricanes and tornadoes.

B.At night, the roles reverse. The air over the ocean is now warmer than the air over the land. The land loses heat quickly after the sun goes down and the air above it cools too. ... This causes the low surface pressure to shift to over the ocean during the night and the high surface pressure to move over the land.

A 55.0 kg bungee jumper steps off a bridge with a light bungee cord tied to her and to the bridge. The unstretched length of the

lianna [129]

Answer:

$69.06\ \text{N/m}$

Explanation:

m = Mass of bungee jumper = 55 kg

g = Acceleration due to gravity = $9.81\ \text{m/s}^2$

h = Height at the bottom = 40 m

k = Spring constant

x = Displacement of bungee cord = 25 m

Applying the principle of conservation of energy to the system we have

$mgh=\dfrac{1}{2}kx^2\\\Rightarrow k=\dfrac{2mgh}{x^2}\\\Rightarrow k=\dfrac{2\times 55\times 9.81\times 40}{25^2}\\\Rightarrow k=69.06\ \text{N/m}$

The spring constant of the bungee cord is $69.06\ \text{N/m}$ .

How many times farther is Proxima Centauri from the sun than is earth from the sun

Aleks04 [339]

Answer:

Of the three stars in the system, the dimmest - called Proxima Centauri - is actually the nearest star to the Sun. The two bright stars, called Alpha Centauri A and B form a close binary system; they are separated by only 23 times the Earth - Sun distance.

A vector A⃗ has a length of 8.6 m and points in the negative x direction. Find the x component of the vector −3.7A⃗ .

77julia77 [94]

Answer:

31.8 m in the positive x-direction

Explanation:

Here we have an example of multiplication of a vector by a scalar.

In order to perform this operation, we have to:

- multiply the magnitude of the vector by the scalar

- reverse the direction of the vector if the scalar is a negative number

In this problem, the original vector has a lenght of 8.6 m and it points in the negative x direction. Now we have to find the vector -3.7A, so we have:

- The magnitude is obtained by calculating the product

$(3.7)\cdot (8.6)=31.8 m$

- The direction is reversed, because the scalar is -3.7, so the new vector will point in the positive x-direction

So the final vector is 31.8 m in the positive x-direction, and therefore its x-component is also 31.8 m in the positive direction.

A car with good tires on a dry road can decelerate (slow down) at a steady rate of about 5.0 m/s2 when braking. if a car is init

Sladkaya [172]

The time required by the car to stop is 4.916 sec.

Since the car is moving with the constant deceleration we can apply the first equation of motion to calculate the time required by the car to stop.

The first equation of motion is given as

V=u+at

Here, V=final speed of the car=0 mi/h as the car stops

u =initial speed of the car=55 mi/hr=24.58 m/s

a= acceleartion =-5 m/s^2 (here negative sign indicates for deceleration)

Now applying the values in the first equation

V=u+at

0=24.58-5*t

t=4.916 sec

Therefore the car will stops in 4.916 sec.
