Answer:
0.391
Explanation:
Since they both have the same diameter, the temperature of both earth's surfaces will be proportional to the solar intensity incident on each surface.
The solar intensity is inversely proportional to the square of their distance.
For true earth Te, distance from the sun is r.
For far Earth Fe, distance from the sun is 1.6r
Solar intensity = power p ÷ area of propagation.
Area of propagation = 4¶r^2 (r is their distances from the sun)
Te = P/(4 x 3.142 x r^2) = p/12.568r^2
TTE is proportional to p/12.568r^2
Fe = p/4¶(1.6r)^2 = p/(4 x 3.124 x 2.56 x r^2) = p/32.174r^2
TFE is proportional to p/32.174r^2
Ratio of TFE/TTE =
p/32.174r^2 ÷ p/12.568r^2
= 32.174 ÷ 12.568 = 0.3906
Approximately 0.391
Answer:
increasing more mass will decrease the acceleration of the skateboarder.
Explanation:
Newton's Second Law states whenever an unbalanced force is applied on an object, it produces an acceleration in the object in the direction of force. This acceleration is directly proportional to force by inversely proportional to mass.
where,
F = Force
a = acceleration
m = mass
If we consider force applied on the skateboarder, then the acceleration is inversely proportional to mass, only.
<u></u>
<u>Therefore, increasing more mass will decrease the acceleration of the skateboarder.</u>
Answer:
Explanation:
We shall use Ampere's circuital law to find magnetic field at required point.
The point is outside the circumference of two given wires so whole current will be accounted for .
Ampere's circuital law
B = ∫ Bdl = μ₀ I
line integral will be over circular path of radius r = 41 cm .
Total current I = 5A -3A = 2A .
∫ Bdl = μ₀ I
2π r B = μ₀ I
2π x .41 B = 4π x 10⁻⁷ x 2
B = 2 x 10⁻⁷ x 2 / .41
= 9.75 x 10⁻⁷ T . It will be along - ve Y - direction.
