Explanation:
1)a=16m
b=28m
c=10m
volume of one box: V=16*28*10=4480m³
volume of 100 boxes: 4480*100=448000m³
2) 1960
3) 7: meter-length, kilogramme-mass, second-time, ampere-electric current, kelvin-temperature, candela-luminous intensity, mole-amount of substance
4)Area: S=a*b
Volume: V=a*b*c
Answer:
(a)
(b)
Explanation:
mass, m = 2.3 kg
vx = 40 m/s
vy = 75 m/s
(a) Angular momentum is given by
Where, p is the linear momentum and r is the position vector about which the angular momentum is calculated.
Here,
So, the angular momentum
(b) Here,
Answer: wind pushes directly against the blades of the turbine, which converts the linear motion of the wind into the rotary motion, then it spins the generator's rotor and the harder the wind pushes, the more electrical energy can be generated.
Explanation:
Answer:
Translational kinetic energy of oxygen gas is 675 J
Explanation:
As we know that translational kinetic energy of ideal gas is given as
also by ideal gas equation we know that
so we have
now we have
so we have
