Answer:
The temperature is 2541.799 K
Explanation:
The formula for black body radiation is given by the relation;
Q = eσAT⁴
Where:
Q = Rate of heat transfer 56.6
σ = Stefan-Boltzman constant = 5.67 × 10⁻⁸ W/(m²·k⁴)
A = Surface area of the cube = 6×(3.72 mm)² = 8.3 × 10⁻⁵ m²
e = emissivity = 0.288
T = Temperature
Therefore, we have;
T⁴ = Q/(e×σ×A) = 56.6/(5.67 × 10⁻⁸ × 8.3 × 10⁻⁵ × 0.288) = 4.174 × 10¹⁴ K⁴
T = 2541.799 K
The temperature = 2541.799 K.
In a collision, there is a force on both objects that causes an acceleration of both objects; the forces are equal in magnitude and opposite in direction. For collisions between equal-mass objects, each object experiences the same acceleration.
The cost of electricity be $ 38.544.
<h3>What is electricity?</h3>
Electricity is the passage of charges in a conductor. From one end of the terminal to the other, charges are transmitted. Usually, the terminal moves from positive to negative. Since the nucleus holds the electrons loosely, they can move freely throughout the body.
Watts are units of power used to measure electrical output.
Price of electricity is $ 0.110 per kWh .
If a 40-W porch light on day and night for a year, total amount of electricity spend = power of the bulb × time
= 40 W × 1 year
= 40 W × 365 day
= 40 W × 365 ×24 h
= 350400 Wh
= 350.4 kWh.
Hence, the cost of electricity be = $350.4 × 0.110 = $ 38.544.
