The two basic defenses in basketball are man-to-man, sometimes referred to as person-to-person in respect for the rise of women's basketball, and zone. Each basic defense has a number of variations.
MA = (Effort Distance)/(Effort Resistance) = L/H
L = MA * H = 5 * 8" = 40"
Answer:
36 N
Explanation:
The tension on the string :
T =mv²/r ------where
m= mass of object = 8 kg
v= tangential velocity = 3 m/s
r= length of the string = 2m
T= [ 8 * 3² ] / 2
T= 36 N
Answer:
transformers
Explanation:
A transformer is a device that increases or decreases voltage.
Surface area is 1.10 × 10^-5 .
Stefan-Boltzmann law, statement that the total radiant heat power emitted from a surface is proportional to the fourth power of its absolute temperature.All bodies radiate energy W depending on temperature T, according to the Stefan-Boltzmann law W = ε σT4 where emissivity ε is equal to 1 for black bodies and less than 1 for grey bodies, σ being the Stefan constant.
From Stefan's law, the power radiated by an object at absolute
temperature T and surface area A is POAT, where a=5.6696 × 10
W/m²K and e is the emissivity. Thus, the surface area of the filament
must be
A =75 W / (5.6696x10 )(1.0 )(3300) = 1.10 * 10^-5
