Answer:
Change in potential energy is 700.7 J.
Explanation:
Given:
Mass of the object is, kg
Height to which the object is raised above his head, m
Acceleration due to gravity is, m/s²
We know that for a mass raised to a height , the change in potential energy is given as:
, where,
Now, plug in the given values and solve.
Therefore, the change in the potential energy is 700.7 J.
Answer:
9.36*10^11 m
Explanation
Orbital velocity v=√{(G*M)/R},
G = gravitational constant =6.67*10^-11 m³ kg⁻¹ s⁻²,
M = mass of the star
R =distance from the planet to the star.
v=ωR, with ω as the angular velocity and R the radius
ωR=√{(G*M)/R},
ω=2π/T,
T = orbital period of the planet
To get R we write the formula by making R the subject of the equation
(2π/T)*R=√{(G*M)/R}
{(2π/T)*R}²=[√{(G*M)/R}]²,
(4π²/T²)*R²=(G*M)/R,
(4π²/T²)*R³=G*M,
R³=(G*M*T²)/4π²,
R=∛{(G*M*T²)/4π²},
Substitute values
R=9.36*10^11 m
Answer:
because hydroelectricity is generate from water and it is considered as a perpetual resources and produce the large capacity of electricity which helps in the indicator of development
No, you would aim slightly above, because when you throw the spear and it travels through the air it will fall slightly downwards by the time it reaches the fish.
The answer best that best describes the relationship between DNA replication and daughter cells is the last one! (DNA replication ensures that each daughter cell has enough chromosomes after mitosis)
