Which answer is consistent with a replacement of light bulb that will increase
the intensity (brightness) of the light in a room
Answer:
What increases the brightness of a light bulb?
Increasing the voltage increases the brightness of the bulb. When a bulb in a series circuit is unscrewed all bulbs in the circuit go out. Increasing the number of bulbs in a series circuit decreases the brightness of the bulbs. ... Bulbs in parallel are brighter than bulbs in series.
A satellite is acted upon by a 10n force upwards and 20n force downwards. What is the net force acting on the satellite and what direction will it move in
Answer:
Net force = 10 N in downward direction
Explanation:
Given that,
Upward force = 10 N
Downward force = 20 N
Let downward is negative and upward is positive.
Net force = 10+(-20)
= -10 N
So, the net force is 20 N and it is acting in downward direction.
if the voltage across a 12 ohm resistor is 4.0 volts. the current through the resistor is?
Answer:
Current = 0.33 Amperes
Explanation:
Given the following data:
Resistance = 12 ohm
Voltage = 4 v
To find the current;
Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
Mathematically, Ohm's law is given by the formula;
Voltage = current * resistance
Substituting into the formula, we have;
4 = current * 12
Current = 4/12
Current = 0.33 Amperes

Two bears sit on a see-saw. The see-saw is 3.5 m in total
length with the fulcrum at the center. A 40 kg baby bear sits at the very end of one side. Where should the 120 kg father bear sit relative to the center to keep the see-saw balanced?
Answer:
Explanation:
For the see-saw to be balanced, take moment at the fulcrum:
40g * 3.5/2 = 120g * distance
distance = 1.167m from the center
25. Suppose there is no unbalanced force acting on a moving object. How will
the object's motion continue?
A. The speed of the object will decrease.
B. The speed of the object will increase.
C. The speed of the object will remain the same.
D. The direction of the object's velocity will change.
Answer:
C
Explanation:
Grammar is probably one of the most important components of the sciences besides math.
no unbalanced forces means that there is no force left over that cause an acceleration. All the forces are balanced.
So the Speed will not decrease. Not A.
The speed will not increase. Not B
The direction will not be affected. Not D
The answer is C

A body is thrown up with with velocity u.it reaches maximum height h. If velocity of projection is doubled the maximum height is..
Answer: 4h
Explanation:
Given
The body is thrown vertically upward with velocity u and reaches a height of h
The relation between u and h is given by
[tex]\Rightarrow v^2-u^2=2as\\[/tex]
Put [tex]v=0,a=-g[/tex] in above equation
[tex]\Rightarrow 0-u^2=2(-g)h\\\\\Rightarrow h=\dfrac{u^2}{2g}[/tex]
If the velocity of projection is doubled i.e. 2u
[tex]\Rightarrow h'=\dfrac{(2u)^2}{2g}\\\Rightarrow h'=4\times \dfrac{u^2}{2g}\\\\\Rightarrow h'=4h[/tex]
The maximum height becomes 4h

explain why does the bowling ball decelerate as it travels along the lane
The main cause of this is Friction. The more oil that is laid down, the less friction there is between the ball and the lane surface. The less friction, the harder it is for the bowler to send the ball in a curved path imparted by the spin that the bowler puts on the ball at the instant of release.

Which type of uninterruptible power supply uses AC power to continuously charge its battery, while also providing power to devices through the battery?
Answer:
An online UPS.
Explanation:
An online UPS is a type of uninterruptible power supply uses AC power to continuously charge its battery, while also providing power to devices through the battery. It combines the inverter and rectifier to provide power to the alternating current (AC) load while supplying alternating current (AC) power during an outage to the load through the inverter.
Basically, an uninterruptible power supply unit is used to provide constant power supply to an electrical device, especially during a power outage.
what factors could enhance memory and kept constant? and why
To help make sure information goes from short-term memory to long-term memory, you can use memory-enhancing strategies. One strategy is rehearsal, or the conscious repetition of information to be remembered. Think about how you learned your multiplication tables as a child.
Proven ways to protect memory include following a healthy diet, exercising regularly, not smoking, and keeping blood pressure, cholesterol, and blood sugar in check. Living a mentally active life is important, too. Just as muscles grow stronger with use, mental exercise helps keep mental skills and memory in tone.
According to one study, mental stimulation like reading can help protect memory and thinking skills, especially as you age. The authors even suggest that reading every day can slow down the late-life cognitive decline. ... The act of reading helps to heighten overall brain function and increase memory.

Two students go to play basketball. They notice the ball is flat (it won't bounce). They decide to pump it up with air. After it is pumped with air, will the ball have more, less, or the same amount of mass as before air was added?
A. The ball has less mass after being pumped with air.
B.Cannot determine unless we measure the mass.
C.The ball has more mass after being pumped with air.
D. The ball has the same amount of mass after being pumped with air.
Justify your answer
The ball has more mass being pumped with air. So, option (C) is correct answer.
What is mass?In physics, mass is a quantitative measurement of inertia, a basic characteristic of all matter. It essentially refers to a body of matter's resistance to changing its speed or location in response to the application of a force. The change caused by an applied force is smaller the more mass a body has. The kilogram serves as the unit of mass in the International System of Units (SI).
As the amount of air is added to the basketball by pumping it up with air, the mass of air is also added with the basketball. Hence, the ball has more mass now.

El siguiente esquema representa un objeto con un volumen de 2cm^3 sumergido en un recipiente que contiene agua. La densidad del agua es 1 g/cm^3 . Si solo la mitad del objeto se encuentra sumergido, el valor de la masa del agua desalojada por el objeto es de:
Answer:
Ver explicación
Explanation:
Según los principios de Arquímedes, el empuje hacia arriba de un objeto sumergido en un fluido es igual al peso del fluido desplazado.
Por eso
Empuje hacia arriba = volumen del objeto * densidad del fluido * aceleración debida a la gravedad
Empuje hacia arriba = 2 * 10 ^ -6 / 2 * 1 * 10 ^ 3 * 10
Empuje hacia arriba = 0.01 N
Desde;
Empuje hacia arriba = peso del fluido desplazado
peso del fluido desplazado = 0.01 N
Masa de fluido desplazado = 0.01 N / 10 = 1 * 10 ^ -3 Kg o 1 g

What is the electric field strenght in units of N/C if the flux through a 2.0m by 1.0m rectangular surface is 396Nm2/C, if the electric field is uniform, and if the plane of the surface is at an angle of π/3 radians with respect to the direction of the field ?
Answer:
The appropriate answer is "396 N/C".
Explanation:
The give values are:
Rectangular surface,
[tex]\Phi_e=396 \ N.m^2/C[/tex]
[tex]a = 2 \ m[/tex]
[tex]b = 1 \ m[/tex]
Angle,
[tex]\theta =\frac{\pi}{3} \ radian[/tex]
Now,
The area of rectangle (A) will be:
= [tex]a\times b[/tex]
= [tex]2\times 1[/tex]
= [tex]2 \ m^2[/tex]
hence,
The electric field strength will be:
⇒ [tex]\Phi_e=E.A Cos \theta[/tex]
or,
⇒ [tex]E=\frac{\Phi_e}{ACos \theta}[/tex]
On putting the given values, we get
⇒ [tex]=\frac{396}{2\times Cos(\frac{\pi}{3} )}[/tex]
⇒ [tex]=\frac{396}{2\times 0.5}[/tex]
⇒ [tex]=\frac{396}{1}[/tex]
⇒ [tex]=396 \ N/C[/tex]
