Answer:
The resolving power remains same.
Explanation:
The resolving power of the lens is directly proportional to the diameter of the lens not on the focal length.
As the diameter is same but the focal length is doubled so the resolving power remains same.
Answer:
They have the same momentum
Explanation:
For the truck,
M = 6160kg
V = 3m/s
Momentum = MV
Momentum = 6160 x 3
Momentum of the truck = 18480kg.m/s
For the car:
M = 1540kg
V = 12m/s
Momentum = MV
Momentum = 1540 x 12
Momentum of the car = 18480kg.m/s
Now we can see from the calculations above, that the truck and car has the same momentum
Answer:
For diatomic oxygen:V=539.06 m/s
For carbon dia oxide:V=459.71 m/s
For dia atomic hydrogen:V=2156.25 m/s
Explanation:
As we know that
Root mean square velocity V
Where
R is the gas constant
T is the temperature (K).
M is the molecular weight.
For diatomic oxygen:
M=32 g/mol
T=273+100 = 373 K
V=539.06 m/s
For carbon dia oxide
M=44 g/mol
T=273+100 = 373 K
V=459.71 m/s
For dia atomic hydrogen:
M= 2 g/mol
T=273+100 = 373 K
V=2156.25 m/s
Net force can help slow down or stop the motion of an object.
Yes, both solid and liquid can be compressed.
