The transfer of heat from the Sun is in the form of thermal radiation (also called infrared radiation)
The transfer of heat at the person’s feet is by thermal conduction. During the day the sand will be hot so if you step on it with bare feet there will be conduction of heat to the feet.
Answer:
900
Explanation:
v = s / t = 9000m / 10 s = 900m/s

Answer:
= 3521m/s
The tangential speed is approximately 3500 m/s.
Explanation:
F = m * v² ÷ r
Fg = (G * M * m) ÷ r²
(m v²) / r = (G * M * m) / r²
v² = (G * M) / r
v = √( G * M ÷ r)
G * M = 6.67 * 10⁻¹¹ * 5.97 * 10²⁴ = 3.98199 * 10¹⁴
r = 32000km = 32 * 10⁶ meters
G * M / r = 3.98199 * 10¹⁴ ÷ 32 * 10⁶
v = √1.24 * 10⁷
v = 3521.36m/s
The tangential speed is approximately 3500 m/s.
He tells you (a speed) per (a time). That's a rate of acceleration .
Let's find out what the acceleration is:
(60 mile/hour) / (6 seconds)
= 10 miles/hour-second
Weird units. Let's convert to something easier.
(10 mi/hr-sec) x (5280 ft/mi) x (1 hr / 3600 sec)
= 14-2/3 ft/sec² = about 0.46 'G'
about 4.47 meter/s²
Answer:
Melt more
Explanation:
I think it will melt more because the water may have more heat present compared to the hot dogs, and we know heat transfer will take place from higher to lower until they've achieved mean temp. or equilibrium.
