Answer:
heat and power
Explanation:
is the simultaneous production of electricity and heat both of which are used
Answer:
7.78 * 10³ m/s
Explanation:
Orbital velocity is given as:
v = √(GM/R)
G = 6.67 * 10^(-11) Nm/kg²
M = 5.98 * 10^(24) kg
R = radius of earth + distance of the satellite from the surface of the earth
R = 2.15 * 10^(5) + 6.38 * 10^(6)
R = 6.595 * 10^(6) m
v = √([6.67 * 10^(-11) * 5.98 * 10^(24)] / 6.595 * 10^(6))
v = √(6.048 * 10^7)
v = 7.78 * 10³ m/s
P1 and P2 are the pressures, and V1 and V2 are the volumes. So you take the first pressure and volume you are given and place them into the equation P1V1 so the first part of the equation would be 101000*0.5 = P2V2. You then rearrange the equation to find what you want, in this instance you would do 50500/0.25 = P2... therefore P2 = 2020000Pa or 2.02*10^6Pa
A = distance traveled by steve in north direction by train = 30 miles
B = distance traveled by steve in east direction by train = 25 miles
R = resultant displacement of the steve relative to starting position
using pythagorean theorem
R = √(A² + B²)
inserting the values
R = √(30² + 25²)
R = 39.05 miles
direction : tan⁻¹(B/A) = tan⁻¹(25/30) = 39.8 deg east of north
