A skydiver reaches terminal velocity. Then he opens his parachute.
What happens to the skydiver as the parachute opens?

Answer:

The correct answer is: 0°C + 0°C = 32°F

Explanation:

We need to remember the conversion equation from Celsius to Fahrenheit:

[tex]y^{\circ}F=(x^{\circ}C * \frac{9}{5})+32[/tex]

In our case x = 0, then y will be:

[tex](0^{\circ}C * \frac{9}{5})+32=32[/tex]

[tex]y=32^{\circ}F[/tex]

Now 0°C + 0°C is just 0°C because if we add a body at a certain temperature to another body with the same temperature the total temperature will the same.

Then, knowing that 0°C = 32°F we can conclude that:

[tex]0^{\circ}C+0^{\circ}C=32^{\circ}F[/tex]

Answer:

142.7650889

Explanation:

I think the answer above is correct. So to find the velocity of the wave you can do: frequency*wavelength = velocity

in your case, the velocity is equal to 403.5m/s

so we know that the 403.52 is the total velocity of the wave

and the equation: velocity at 0 degrees Celsius * [tex]\sqrt{{T}/{273}}[/tex] where T represents temperature in Kelvins = veloctity

so we set 403.52 = 327*[tex]\sqrt{{T}/{273}}[/tex] and solve for T

T will then equal the degree in Kelvins

so to convert from Kelvins to degrees celsius you subtract 273 from the Kelvins value and you are left with the degrees in Celsius which equals 142.7650889 degrees Celsius

Answer:

If you hold a compass near a wire through which current is flowing, the needle on the compass will be deflected. Since compasses work by pointing along magnetic field lines, this means that there must be a magnetic field near the wire through which the current is flowing

Explanation:

it seems white because once it falls or hits the bottom bubbles are created and it makes it look white

Answer:

However, when water flows rapidly, its flow becomes turbulent. This sort of aeration creates tons of small bubbles in water, which are eventually responsible for the white color of waterfalls.

The scientists who discovered them will start things off by proposing a name. But it will be down to the International Union of Pure and Applied Chemistry (IUPAC) to approve it.

I'm slow...

Newly discovered elements often occur at the bottom of the groups where they occur in the periodic table hence they must have very high atomic numbers.

In the periodic table, the properties of elements are arranged in increasing order of their atomic numbers according to the modern periodic law. As you move down the group, the atomic numbers of elements continue to increase.

Since the properties of elements are periodic, newly discovered elements often occur at the bottom of the group hence they have very high atomic numbers.

Answer:

v_f = 3 m/s

Explanation:

From work energy theorem;

W = K_f - K_i

Where;

K_f is final kinetic energy

K_i is initial kinetic energy

W is work done

K_f = ½mv_f²

K_i = ½mv_i²

Where v_f and v_i are final and initial velocities respectively

Thus;

W = ½mv_f² - ½mv_i²

We are given;

W = 150 J

m = 60 kg

v_i = 2 m/s

Thus;

150 = ½×60(v_f² - 2²)

150 = 30(v_f² - 4)

(v_f² - 4) = 150/30

(v_f² - 4) = 5

v_f² = 5 + 4

v_f² = 9

v_f = √9

v_f = 3 m/s

Answer:

Momentum = 2,400 Pa

Explanation:

Given:

Total mass = 60 kg

Distance travel = 200 m

Time = 5 sec

Find:

Momentum

Computation:

Velocity = Distance / time

Velocity = 200 / 5

Velocity = 40 m/s

Momentum = Mass x Velocity

Momentum = 60 x 40

Momentum = 2,400 Pa

Answer:

Only at point a

Explanation:

If the velocity is greater than zero, than the object must be moving.

Answer:

I'm not sure but I think it is electric currents in the outer core

Answer:

85.8 m/s

Explanation:

We know that the length of the circular path, L the plane travels is

L = rθ where r = radius of path and θ = angle covered

Now,its speed , v = dL/dt = drθ/dt = rdθ/dt + θdr/dt

where dθ/dt = ω = angular speed = v'/r where v' = maximum speed of plane and r = radius of circular path

Now, from θ = θ₀ + ωt where θ₀ = 0 rad, ω = angular speed  and t = time,

θ = θ₀ + ωt = 0 + ωt = ωt

So, v = rdθ/dt + θdr/dt

v = rω + ωtdr/dt

v = (r + tdr/dt)ω

v = (r + tdr/dt)v'/r

v = v' + tv'/r(dr/dt)

v = v'[1 + t(dr/dt)/r]

Given that v' = 110 m/s, t = 33.0s, r = 120 m and dr/dt = rate at which line is shortened = -0.80 m/s (negative since it is decreasing)

So, v = 110 m/s[1 + 33.0 s(-0.80 m/s)/120 m]

v = 110 m/s[1 + 11.0 s(-0.80 m/s)/40 m]

v = 110 m/s[1 + 11.0 s(-0.02/s)]

v = 110 m/s[1 - 0.22]

v = 110 m/s(0.78)

v = 85.8 m/s

Answer:

A. A train traveling 60 miles per hour.

Explanation:

Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.

Mathematically, momentum is given by the formula;

[tex] Momentum = mass * velocity [/tex]

This ultimately implies that, the mass of an object or body is directly proportional to its momentum. Thus, the higher the mass of an object or body, the greater would be its momentum and vice-versa.

Hence, a train traveling 60 miles per hour would have the most momentum because it has the greatest mass among the other objects (options).

Answer:

False

Explanation:

Neither the USGS nor any other scientists have ever predicted a major earthquake. USGS scientists can only calculate the probability that a significant earthquake will occur in a specific area within a certain number of years.

When you get out of bed in a morning it's most likely too be cold so your bare feet on a floor not carpet a bare floor will feel cold since the temperature and molecules had changed and if you step on a warm fuzzy rug it will feel warm since your feet are cold and the rugs fuzziness or material keeps you warn

We feel more cold on feet on morning because heat from our feet will flow to the cold floor. We feel more cold on the bare floor than the rug since it conducts heat away from our feet.

Heat will be transfer on a temperature gradient from one substance to the other.  Heat is transferring from the hot body to the colder body. There are three types of heat transfer are there namely, conduction, convection and radiation.

Conduction is the heat transfer in solids , convection in liquids and radiation is the heat or energy transfer mode in gases and vacuum.  At the morning, the floor will be more cool whereas our body will be hotter, thus heat will flow our body to floor make our feet cool.

A bare floor will conduct thermally more than a rug do. Thus the bare floor conducts heat away from our feet and make our feet more cool.

Answer:

80%.

Explanation:

Question didn't state what is being looked for, but then....

Weight of the box, w = 100 N.

Length of the plane, L = 5 m

Force used, = 75 N

Length pushed through, = 3 m

Looking at the stated parameters, the first thing that comes to mind is to look or calculate for the efficiency of the machine.

Tha efficiency can be gotten by using the relation

Change in energy divided by work done. This is gotten by saying

(100 * 3) / (5 * 75) =

300/ 375 = 0.8

Therefore, the efficiency of the machine has been calculated to be 80% or 0.8
