Answer:
<h2>
They would draw a total of 21.25 amperes</h2>
Explanation:
The total power consumed is
1200 W+ 750 W + 600 W= 2550 Watts
The formula relating the power consumed, the voltage and the current is given as
---------------1
given that the voltage supply is 120V
The volume is given by:
V = Ad
V = volume, A = surface area, d = depth
Given values:
A = 116214700km² = 1.162147×10¹⁸cm², d = 3940m = 394000cm
Plug in and solve for V:
V = 1.162147×10¹⁸(394000)
V = 4.57885918×10²³cm³
Microwave and Infrared Radiation. Both are forms of electromagnetic radiation. Both are transmitted as waves. Waves are converted to heat.
Answer: 0.02kg
Explanation:
The quantity of heat energy (Q) required to heat a substance depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)
Thus, Q = MCΦ
Since,
Q = 50 joules
Mass of iron sample = ? (let unknown value be Z)
C = 100 J/kg°C
Φ = 25°C
Then, Q = MCΦ
50J = Z x 100 J/kg°C x 25°C
50J = 2500J/kg x Z
Z = (50J/2500J/kg)
Z = 0.02kg
Thus, the mass of the iron sample is 0.02kg
B: new technology allowed microscopes to make it easier to view things that had never been seen before, such as cells
C: new technology allowed microscopes to produce still images on a computer screen
D: new technology allowed to create realistic three-dimensional pictures
E: new technology allowed microscopes to map the atom on the surface of an object
