<span>Δ PE = m g ( h1 - h2 ) = 0.25 * 9.8 ( 0.541 - 0.127 ) = 2.45 * 0.414 = 1.0143 J Δ PE = KE = 1 / 2 m V^2 1 / 2 m V^2 = 1.0143--- v^2 = 1.0143 * 2 / 0.25 = 8.1144 --- v= 2.8486 m/s</span>

Your bedroom gets direct sunlight through a window during the hottest part of the day. You ask your mom to turn down the thermom
ycow [4]
I want to say its cooled by reflection because of the foil, sun reflects off of the foil back into the atmosphere. I don't think it's conduction because I have the foil on my windows and it's never warm to the touch. it's not a liquid so I don't believe it's convection. The foil reflects the radiation so I don't think it's b, c or d. so I wanna say A but I'm not 100% sure

The whale shark is the largest of all fish and can have the mass of three adult
ch4aika [34]

Answer:

m = 20,000 kg

Explanation:

Force, F=2.5\times 10^4\ N

Acceleration of the shark, a=1.25\ m/s^2

It is required to find the mass of the shark. Let m is the mass. Using second law of motion to find it as follows :

F = ma

Putting the value of F and a to find m

m=\dfrac{F}{a}\\\\m=\dfrac{2.5\times 10^4}{1.25}\\\\m=20,000\ kg

So, the shark's mass is 20,000 kg.
