Answer:
Explanation:
for earth -sun system
E = σ T⁴ , E is radiation emitted by sun at temperature T
E = 4π R₁² x solar constant on earth , R₁ is distance between earth and sun.
for marsh -sun system
E = σ T⁴ , E is radiation emitted by sun at temperature T
E = 4π R₂² x solar constant on Mars , R₂ is distance between earth and sun.
from two equation ,
4π R₂² x solar constant on Mars = 4π R₁² x solar constant on earth
solar constant on Mars = (R₁ / R₂ )² x solar constant on earth
Answer:
100 m/s
Explanation:
Mass the mass of Bond's boat is m₁. His enemy's boat is twice the mass of Bond's i.e. m₂ = 2 m₁
Initial speed of Bond's boat is 0 as it won't start and remains stationary in the water. The initial speed of enemy's boat is 50 m/s. After the collision, enemy boat is completely stationary. Let v₁ is speed of bond's boat.
It is the concept of the conservation of momentum. It remains conserved. So,
Putting all the values, we get :
So, Bond's boat is moving with a speed of 100 m/s after the collision.
Answer: rolling friction
Explanation: I think it is the answer
Answer:
2 × 10⁵
Explanation:
The total mass of the drug, ibuprofen = 10 kg
Kilograms and grams are related as:
1 kg = 1000 g
Also,
Grams and milligrams are related as:
1 g = 1000 mg
So,
1 kg = 10⁶ g
Mass of the drug, ibuprofen = 10 × 10⁶ mg = 10⁷ mg
Given, mass of tablet = 50 mg
So, number of tablets = total mass / Mass of 1 tablet = 10⁷ mg / 50 mg = 2 × 10⁵
<u>Number of 50 mg tablets = 2 × 10⁵</u>
