<h2>
Answer: evaporation</h2>
Explanation:
Evaporation fog occurs when surface air is much colder and relatively less saturated than water. Then, when the water evaporates, it inmediately condenses again in small drops of water that stay suspended very close to this body of water.
In other words: This type of fog occurs when cold air moves over warmer water. And it is this difference in temperature that contributes to the formation of fog over the lakes, especially near the polar regions.
Answer:
60 to 80%
Explanation:
For maximum benefit, the heart rates during exercise regimes should be between<u> 60 to 80% </u>of an individual's maximum heart rate.
<em>The maximum heart rate varies from individuals to individuals and largely depends on age. It is calculated by subtracting one's age from 220. For example, a person that is 40 years old would have a maximum heart rate of;</em>
<em> 220 - 40 = 180 beats per minute.</em>
Such a person's heart rates during exercises should be between 108 and 144 beats per minute for maximum benefits.
Answer:
the second one i guess????
Explanation:
Answer:
The value is 
Explanation:
From the question we are told that
The velocity of the each of the three cars is 
The velocity of the fourth car is 
The initial velocity of the fifth car 
Generally from the law of momentum conservation we have that
![m_1 u_1 + m_2 u_2 + m_3 u_3 +m_4u_4 + m_5u_5 = [m_1 + m_2 + m_3 +m_4+ m_5]v](https://tex.z-dn.net/?f=m_1%20u_1%20%2B%20m_2%20u_2%20%2B%20m_3%20u_3%20%2Bm_4u_4%20%2B%20m_5u_5%20%3D%20%20%5Bm_1%20%20%20%2B%20m_2%20%2B%20m_3%20%2Bm_4%2B%20m_5%5Dv)
Given that the cars are identical then their mass will be the same
i.e
=> ![[u_1 + u_2 + u_3 +u_4 + u_5]m = 5mv](https://tex.z-dn.net/?f=%5Bu_1%20%2B%20u_2%20%2B%20%20u_3%20%2Bu_4%20%2B%20u_5%5Dm%20%3D%20%205mv)
=> 
= >
A student uses a meter to measure 120 coulombs flowing through a circuit in 60 seconds. The electric current in this circuit will be 2 A
Current is a flow of electrical charge carriers, usually electrons or electron-deficient atoms. The common symbol for current is the uppercase letter I. The standard unit is the ampere, symbolized by A.
current = charge / time
given
time = 60 seconds
charge = 120 Coulombs
current = Q / T = 120 / 60 = 2 A
