None of the given options is correct based on the relationship for the components of the crate's weight.
The given parameter:
- <em>Angle of inclination, = q</em>
The vertical component of the force on the crate is calculated as follows;
The horizontal component of the crate is calculated as follows;
Thus, we can conclude that none of the given options is correct based on the relationship for the components of the crate's weight.

Answer:
<em>Venus will need to use more voltage to have the same current</em>
Explanation:
<u>Ohm's Law</u>
It states that the current through a conductor is directly proportional to the voltage applied to it and inversely proportional to the resistance of the conductor. This relationship can be written as
Solving for V
Venus originally connected a resistance to a voltage to get some current I
The voltage needed to get that current is
If Venus changes the light bulb to another with higher resistance, say, , then the current would change, unless she uses another voltage
Venus will need to use more voltage to have the same current
Answer:
A. Remove everything in the refrigerator to lighten the load.
B. Put a lubricant between the surface of the object and the floor
C. Use round objects, like pencils , to decrease the friction and push the refrigerator over the pencils more easily
Explanation:
Force of friction is a resistance force which acts between two surfaces which are in relative motion. Friction is both boon and bane. Due to friction, we are able to sit, walk etc but also, due to friction there is dissipation of energy. Friction can be reduced by applying lubricants, reducing contact area, reducing the load.
F = μN where N is the normal force which depends on the mass.
Thus, by reducing the load, force of friction can be reduced. Round objects like wheels can also be used. By this the contact area reduces.
It's called induced charge separation I believe.
Answer:
Las moléculas en el aire dispersan más la luz azul del sol que la luz roja. Cuando miramos hacia el sol al atardecer, vemos colores rojo y naranja porque la luz azul se ha dispersado y lejos de la línea de visión.
