Answer: energy source, path, and load
Explanation:
2g/mL
Explanation:
Given parameters :
Mass = 10g
Volume = 5mL
Unknown:
Density of the object = ?
Solution:
Density is defined as the mass per unit volume of a body.
Density = 
Now, input the values in the equation:
Density =
= 2g/mL

Answer:
To investigate into how the height of a ramp affects the speed of a toy car rolled down a hill or slope because the higher the ramp the more Gravitational potential Energy (GPE), the more kinetic energy converted and the car will go faster. So the ramp increases, the velocity will also increase.
Explanation:
Answer:
65.9°
Explanation:
When light goes through air to glass
angle of incidence, i = 35°
refractive index, n = 1.5
Let r be the angle of refraction
Use Snell's law


Sin r = 0.382
r = 22.5°
Now the ray is incident on the glass surface.
A = r + r'
Where, r' be the angle of incidence at other surface
r' = 60° - 22.5° = 37.5°
Now use Snell's law at other surface

Where, i' be the angle at which the light exit from other surface.

Sin i' = 0.913
i' = 65.9°
