Answer:
a force
Explanation:
Because if we apply force then only an object can slow down, speed up or change direction
Answer:
1/4 times your earth's weight
Explanation:
assuming the Mass of earth = M
Radius of earth = R
∴ the mass of the planet= 4M
the radius of the planet = 4R
gravitational force of earth is given as = ![\frac{GM}{R^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7BGM%7D%7BR%5E%7B2%7D%20%7D)
where G is the gravitational constant
Gravitational force of the planet = ![\frac{G4M}{(4R)^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7BG4M%7D%7B%284R%29%5E%7B2%7D%20%7D)
=![\frac{G4M}{16R^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7BG4M%7D%7B16R%5E%7B2%7D%20%7D)
=![\frac{GM}{4R^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7BGM%7D%7B4R%5E%7B2%7D%20%7D)
recall, gravitational force of earth is given as = ![\frac{GM}{R^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7BGM%7D%7BR%5E%7B2%7D%20%7D)
∴Gravitational force of planet = 1/4 times the gravitational force of the earth
you would weigh 1/4 times your earth's weight
You are correct earth science is studied to predict planetery changes
From the planks equation
E=hv
V= c/ wave length
V= 3×10^8/30×10^-9
=1×10^16
E= hv
6.63×10^-34×1×10^16
= 6.63×10^-18
