the weight of the balloon is .030 * 10 = 0.3 N
the weight of the gas of volume v is 0.54*10 N
The lifting force of a volume of v m³ of displaced air is 1.29v N
so, we need
1.29*10*v = 0.3 + 0.54*10*v
or
1.29v = 0.03+0.54v
Answer:
Since velocity is a speed and a direction, there are only two ways for you to accelerate
Explanation:
change your speed or change your direction—or change both.
Answer:
Angle Of Incidence Formula The angle of incidence is equal to the reflected angle through the law of reflection. The angle of incidence and the angle of reflection is always equal, and they are both on the same plane along with the normal. 2,44,451
Explanation:
that could help you with work.
Answer: 3976N
Explanation:
Using the formula for calculating gravitational force between two masses, we have
F = GMm/r^2
Where G is the gravitational constant
M and m are the masses
r is the distance between the masses
F= 6.673 × 10-¹¹ × 5.98 × 10²⁴ × 63.5/ (6.37 × 10^6)^2
F= 2.533×10^16/6.37×10^12
F= 0.3976×10⁴N
F= 3976N
Answer:
Daily Cost = 24 ¢
Explanation:
Consider a typical incandescent bulb having a power rating of 100 W. Now, we calculate the daily consumption by multiplying the Power with time:
Daily Consumption = (Power Rating)(Time in hours)
Daily Consumption = (0.1 KW)(24 h/1 day)
Daily Consumption = 2.4 KWh
Now, we will calculate the daily cost of the incandescent lamp by multiplying the daily consumption with the unit cost.
Daily Cost = (Daily Consumption)(Unit Cost)
Daily Cost = (2.4 KWh)(10 ¢/KWh)
<u>Daily Cost = 24 ¢</u>
