Kinda but a football field is 100 yds. (91.4m), so not really because a Wide Receiver doesn't usually run down the entire field in one play. Also they have to pace themselves because they have to run more than one play in a whole game.
It should be A since a cold front develops when a cold air mass moves into an area with warmer air.
V=IR
Total resistance R=2.5*4=10ohms
15=I*10
I=1.5 amps
Power=I^2R where R here is one lamp so
P=1.5^2*2.5=5.625 Watts
Answer:
C. Sunlight to electricity
Explanation:
Photo voltaic cells covert sunlight to the electricity. It absorbs the light from the sun and use that sunlight to create electric current. The number of photo voltaic cells are connected together in a solar panel to generate enough electricity to power up a home.
Answer:
0.26
Explanation:
Given that :
Diameter of ball = 3.81 cm = 3.81/100 = 0.0381 m
Radius (r) = 0.0381 / 2 = 0.01905 m
Average density of ball (Db) = 0.0842 g/cm³ = (0.0842 / 1000)kg / 10^-6 = 0.0842/ 1000 * 10^6 = 84.2kg/m³
Density of water (Dw) = 1000kg/m³
Volume of hollow ball: (4/3) * pi * r³
V = (4/3) * π * 0.01905^3
V = 0.0000289583 m³
Required force = (Dw * V * g) - (Db * V * g)
= (1000 * 0.0000289583 * 9.8) - (84.2 * 0.0000289583 * 9.8)
= 0.259896109172
= 0.2598 N
