How does solar radiation affect climate?
Solar radiation hitting the earth, a sphere which is tilted on its axis, puts into effect differential heating of the earth's surface. This affects weather and climate<span> all across the globe.
</span>
how does ocean currents affect climate?
<span> currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.</span>
The answer
the number of moles can be found easily by using formula of molar mass
Molar mass = mass (g) / number of moles (mol)
from this, we can get number of
number of moles (mol) =mass (g) / Molar mass
the mass molar of <span>(NH4)2S :
M(</span><span>(NH4)2S) = (14+ 4x1) x 2 + 32 = 36+32 = 48 g/ mol
</span>
number of moles (mol) = <span>150 g / 48 = 3.12 moles</span>

Answer:</h3>
- She needs to know how long it took for her mom to get to her destination.
- She needs to know how far her mom drove.
<h3>
Explanation:</h3>
- Velocity is a vector quantity, which means it has both magnitude and direction.
- It is the ratio of displacement to time taken.
That is; Velocity = Displacement ÷ Time taken
In our case;
Malika needs to determine the velocity of her mom's car.
- Apart from knowing the direction the car travels, she also needs to know the time it takes her mom to reach her destination and how far her mom drove.
- Therefore, if it took her mom time, t seconds to drove for a distance, d meters. Then her mom's car velocity would be;
Velocity, v = d/t m/s
