D=(1/2) x at^2. d=(1/2)(4)(20)^2. 2(400)=800 m. In kilometers, the answer is 0.8 km. A. You're welcome. ;)
D, because the hairdryer uses a fan
E, because it produces heat
Answer:
396.97°C
Explanation:
Charles' Law explains that at constant volume, the pressure of an ideal gas is directly proportional to its temperature (in Kelvin).
P₁ ∝ T₁
P₁ = kT₁
k = constant of proportionality
(P₁/T₁) = (P₂/T₂)
P₁ = 240.0 kPa
T₁ = Boiling point of water = 100°C = 373.15 K
P₂ = 431.0 kPa
T₂ = ?
(240/373.15) = (431/T₂)
T₂ = (431 × 373.15) ÷ 240
T₂ = 670.12 K
T₂ = 396.97°C
Hope this Helps!!!
Yes
Explanation:
There would be a difference in temperature between the two places over the time interval.
What is temperature?
Temperature is the degree of hotness or coldness of a body. It is measured using a thermometer as described in the set up.
Temperature changes is a result of heat transfer.
The sun is the ultimate source of energy for the earth.
It transfers heat to the earth by radiation.
Under a shade, the tree leaves or shed will cut off the radiation preventing it from reaching the surface. This place will be cool and at a lower temperature than expected.
The thermometer furnished with direct sunlight will have a higher temperature. As the radiation from sun hits the surface, it causes it to warm up and increase in temperature. This will cause the thermometer's temperature to also rise.

E = mc²
E = 0.235 kg · (3×10⁸ m/s)² = 0.235 · 9×10¹⁶ kg·m/s²
E = 2.115×10¹⁶ J
The answer is d) 2.12×10¹⁶ J
