Answer:
877
Explanation:
P1 = 150 atm
V1 = 0.12 m^3
P2 = 1.2 atm
V2 = ?
radius of each balloon, r = 0.16 m
Volume of each balloon,
V2 = 0.0171 m^3
Let the number of balloons be N.
So,
P1 x V1 = N x P2 x V2
150 x 0.12 = N x 1.2 x 0.0171
N = 877.19
So, the number of balloons be 877.
Answer:
intensity is 8.9 x W/m²
power is 11.3 x W
Explanation:
Given data
distance = 20 light year
power output = 4.00 x 10^28
to find out
intensity of the starlight and the power of the starlight
solution
we know the intensity formula that is
intensity = power / area
so here power is 4.00 x 10^28 and area = 4π(20ly)²
intensity = 4.00 x 10^28 / (4π (20×9.46×10^15)²
intensity = 8.9 x
so intensity is 8.9 x W/m²
and
power is Intensity × Area
so power = 8.9 x × (π (6.37 × 10^6)²
power = 11.3 x
so power is 11.3 x W
Answer:
Explanation:
We just have to calculate what angular displacement a ball with an average angular velocity of 290 rev/min experiments in 0.64s. By definition, angular velocity is the angular displacement divided by the time elapsed:
Since and , we can covert:
Where the terms between parenthesis are equal to 1, so they just change the units. Then for our values we have:
I think it is electron. Electrons are located outside of the nucleus
Answer:
The aim of layout is both to present information in a logical, coherent way and to make the important elements stand out. An additional, more understated benefit, is that a well-designed layout can make the content easier to understand.
