One cubic meter (1.00 m) of aluminum has a mass of 2.70 10 kg, and the same volume of iron has a mass of 7.8610'kg. Find the rad
us of a solid aluminum sphere that will balance a sod irn sphere o radu 14 squal-a balano rm
1 answer:
Answer:
Radius of aluminium sphere which has same mass as of sphere of iron with radius 14 m is 40.745 meters.
Explanation:
Let the radius of aluminium sphere be
From the relation between density, mass and volume we know that
Applying equation 'i' separately to iron and aluminium sphere we get
Equating the masses of iron and aluminium spheres we get

Answer:
W = V Q energy = work / charge * charge
Q = I t charge = current * time
V = W / (I * t)
V = 3 * 10E8 J / (1.5 * 10E4 amps * 2 * 10E-4 sec)
V = 10^8 volts

Answer:
Explanation:
As we projected the balloon at speed vo at an angle of 29 degree
so the two component of velocity is given as
now we know that in x direction we have
in y direction we have
now we have
Elastic collision is when kinetic energy before = kinetic energy after
Ek= 1/2mv^2
total before
Ek=1/2(2)(2.2^2) = 4.84 J
total after
Ek= 1/2(2+4)(v^2) = 3v^2
Before = after
4.84=3v^2 | divide by 3
121/75 = v^2 | square root both sides
v=1.27 m/s
