D.
Have a longer revolution time since they definitely do not get warmer, They do not have fewer moons (Jupiter has about 100 and earth has 1) they are not smaller in diameter (Earth v Jupiter)
B.
An interjection, most likely along the lines of "Ow" or "Ouch", would follow after stubbing one's toe.
Also, this seems to be an English question as opposed to a physics one; just noting.
Hi Davina :) Yes, partial reflection and refraction will occour because the incident ray will refract if it has not reached the critical angle. Once the ray reaches the critical angle of the first media they ray will start to totally internally refract, in summary. Yes it will unless the angle is past the critical angle
Answer:
Magnitude force of friction is 235.2 N
Explanation:
The force of friction is the product of weight and the coefficient of static friction
The force have to be bigger than 200N because it don't move
∑F=
N
The force on the filling cabinet
Answer:
c
Explanation:
Since he shells of scallops make them denser than water, they normally rest on the ocean floor, which means there is a force needed to overcome the gravitational pull, which pullls them towards the ocean flootr. To hover in the water they must use their yet propulsion to push upwards ( otherwise they sink to the floor again).
To be able to create an upward force, the yet propulsion needs to eject water downwards. Every action has the same and opposite reaction (Third law of Newton).
