M= 130 kg
v= 5 m/s
kinetik energy = ½• m•v²
= ½ • 130• 5²
= ½•130•25
= ½•3250
= 1625.
Engineers must understand the thermal properties of materials to be able
to predict the performance of any given material over its lifetime in a
specific application. Engineers apply their understanding of the
thermal properties of materials to the design of efficient heat transfer
materials for better engines, spacecraft and electronic devices. They
also examine the thermal properties of insulation to design more
efficient buildings and homes. Engineers develop ways to minimize heat
transfer from a motor to the surrounding environment. Often they find
ways to insulate the motor to decrease the convective heat transfer from
the motor. They design a refrigerator to keep heat out of the inside,
as well as keep the refrigerator contents cool. hope this helped
Answer: I am pretty sure it is (b) what is the value of mass suspended at the end of the spring.
Explanation:
Answer: The gravitational force Fg exerted on the orbit by the planet is Fg = G 4/3πr3rhom/ (R1 + d+ R2)^2
Explanation:
Gravitational Force Fg = GMm/r2----1
Where G is gravitational constant
M Mass of the planet, m mass of the orbit and r is the distance between the masses.
Since the circular orbit move around the planet, it means they do not touch each other.
The distance between two points on the circumference of the two massesb is given by d, while the distance from the radius of each mass to the circumferences are R1 and R2 from the question.
Total distance r= (R1 + d + R2)^2---2
Recall, density rho =
Mass M/Volume V
Hence, mass of planet = rho × V
But volume of a sphere is 4/3πr3
Therefore,
Mass M of planet = rho × 4/3πr3
=4/3πr3rho in kg
From equation 1 and 2
Fg = G 4/3πr3rhom/ (R1 + d+ R2)^2
