If light travels from oil to water at an angle, what happens to the direction of the light ray in water with respect to the normal, is it moves away from the normal.
Answer:
The maximum speed of car will be 20.5m/sec
Explanation:
We have given mass of car = 1100 kg
Radius of curve = 82.3 m
Static friction 
We have to find the maximum speed of car
We know that at maximum speed centripetal force will be equal to frictional force 

So the maximum speed of car will be 20.5m/sec
Answer:
3.05×10⁵ Nm²C⁻¹
Explanation:
According to Gauss' law,
∅' = q/e₀............... Equation 1
Where ∅' = net flux through the surface, q = net charge, e₀ = electric permittivity of the space
From the question,
Given: q = 2.7 μC = 2.7×10⁻⁶ C,
Constant: e₀ = 8.85×10⁻¹² C²/N.m²
Substituting these values into equation 1
∅' = (2.7×10⁻⁶)/(8.85×10⁻¹²)
∅' = 3.05×10⁵ Nm²C⁻¹
Answer:
a) a = 3.29 m/s²
b) a = 3.51 m/s²
Explanation:
mass of dogs = 19 kg
loaded sled mass = 210 Kg
a)writing all the forces in x direction

a = 3.29 m/s²
b) acceleration when sled start to move the friction will now be acting will be kinetic friction.

a = 3.51 m/s²
Answer:
En el deporte, la persona que lo práctica tiene que adecuarse a él, por el contrario cuando hablamos de actividad física el objetivo pasa por programar, dosificar y adecuar en entrenamiento a las características, necesidades y objetivos de cada persona.
