Answer:
The solid ball and hollow ball both will reach the bottom with the same speed.
Explanation:
The speed of the solid and hollow balls is independent of the mass and the radius. A solid and hollow ball experience same speed on a given incline.
The speed can be calculated as
v = √(10/7)gh
where g is gravitational acceleration and h is the height
sinθ = h/L
h = L*sinθ
h = 3*sin(35)
h = 1.72 m
v = √(10/7)*9.8*1.72
v = 4.91 m/s
Both balls will reach the bottom at the speed of 4.91 m/s.
True
Most photographs will be made using a shutter speed of 1/60 or faster.
A toaster draws electric current (electrical energy) from a wall outlet and converts these moving electric charges into heat (thermal energy) in the filaments that turn red hot to cook your toast. ... As electricity runs through the filaments in a space heater, the electrical energy is converted into heat (thermal energy).
Hopefully this helped.
Its good for a scientist to be skeptical because they dont willingly accept new ideas without thoroughly going over the research themselves and attempting to disprove a theory. skeptical scientists often reveal new information through doing their own examinations of a concept, which is why they are valuable scientists
