Answer:

Option 3

Explanation:

Carbon is cycled into the hydrosphere through the diffusion from the atmosphere.

Further explaining this :

Some of the carbon dioxide molecules in the rain react with the water droplets to form carbonic acid that falls with the rain. The carbonic acid that falls to the surface of the Earth dissolves rocks by the process of chemical weathering, where it releases calcium, magnesium, potassium or sodium ions. These ions are carried by rivers to the ocean. The carbonic acid that falls directly into surface water bodies reacts with the water to form bicarbonate ions.

ehidna [41]

Answer:5.21 N

Explanation:

Given

B=5.210 T

I=2 A

L=0.5 m

Given Wire is perpendicular to Magnetic field

$\theta =90^{\circ}$

$F=IL\times B$

$F=BIL sin\theta$

$F=5.210\cdot 2\cdot 0.5 sin(90)$

F=5.210 N

as 1 Tesla =1 N/A/m

A car is stopped at a red light. When the light turns green, the car accelerates until it reaches a final velocity of 45 m/s. It

tigry1 [53]

Answer:

270 m

Explanation:

We can find the distance travelled by the car by using the following suvat equation:

$s=(\frac{u+v}{2})t$

where

s is the distance travelled

u is the initial velocity

v is the final velocity

t is the time

For the car in this problem,

u = 0

v = 45 m/s

t = 12 s

Substituting into the equation, we find:

$s=(\frac{0+45}{2})(12)=270 m$

A car starts at zero and gets to 50 km/hour in 10 minutes. What is the initial velocity?

gladu [14]

The initial velocity is the speed and direction of the car at the beginning
of the event.

You just said that the car "starts at zero". You might mean that it starts at
"location zero". But then you go on to tell us its speed after 10 minutes,
so it sounds like the "zero" at which it starts is zero speed.

In that case, its initial velocity is zero.
