Answer:
9194.4278 seconds
Explanation:
Orbital period is given by :
T² = (4π²r³) /GM
G = Gravitational constant = 6.67 * 10^-11
M = 5.9801 * 10^24 kg
r = (3.110 * 10^6 m + 6378000 m) =3110000 + 6378000 = 9488000 m
T² = (4π² * 9488000^3) / (6.67* 10^-11 * 5.9801*10^24)
T² = 3.37197 * 10^22 / 398872670000000
T² = 84537504.161415
T = sqrt(84537504.161415)
T = 9194.4278 seconds
Answer:
Explanation:
An example of an intense aerobic activity would be running/ sprinting sprinting targets six specific muscle groups: hamstrings, quadriceps, glutes, hips, abdominals and calves. Sprinting is a total body workout featuring short, high-intensity repetitions and long, easy recoveries.
Answer:
(a) for 43.75 mm rod, the temperature is 121.97 ⁰C
(b) for 87.50 mm rod, the temperature is 80.17 ⁰C
(c) for 175.00 mm rod, the temperature is 53.46 ⁰C
Explanation:
Given;
L = 175 mm = 0.175 m
D = 5mm = 0.005
= 200°C
T∞ = 20°C
Heat transfer coefficient h = 30 W/m²·K
Thermal conductivity of brass K = 133 W/m.°C
where;
T is the temperature of the rod at different casting distance,
Part (a) for 43.75 mm rod
Part (b) for 87.50 mm rod
Part (c) for 175.00 mm rod
The work done is 46 J
Explanation:
The work done by a force pushing a body is given by
where
F is the magnitude of the force
d is the displacement of the body
is the angle between the directions of the force and of the body
In this problem:
F = 23 N
d = 2 m
(we assume the force is parallel to the displacement)
Therefore, the work done is
