A lamp is plugged into a standard 120-volt outlet. If the lamp draws a current of 0.5-amps, how much energy is consumed in 1 minute? A) 3600 joules B) 240 joules C) 60 joules D) 1 joule

First, we can calculate the power used by the lamp, which is given by the product between the voltage and the current:
P=VI=(120 V)(0.5 A)=60 W

Now, we know that the energy used is the product between the power and time. The time interval is 1 minute, which corresponds to 60 s, therefore the energy used during this time is
E=Pt=(60 W)(60 s)=3600 J

Therefore, A) is the correct answer.

According to Sternberg, consummate love includes:

This is the answer:

B. intimacy, commitment, and passion

These three are the components of love in Sternberg's Triangular Theory of Love.

Hope this helps.
Solution 2

Answer:

The correct answer is B. According to Sternberg, consummate love includes intimacy, commitment, and passion.

Explanation:

The triangular love theory of the American psychologist Robert Sternberg characterizes love in an interpersonal relationship according to three different components, which are intimacy, passion and commitment:

-Intimacy, understood as those feelings within a relationship that promote the approach, the link, the connection and mainly the self-revelation. Or in other words, the affection towards another person that arises from feelings of closeness, affective bond and relationship, implies the desire to give, to receive, to share, and so on.

-Passion, as a state of intense desire for union with the other, as an expression of desires and needs, great sexual or romantic desire accompanied by psychological excitement.

-Commitment, the decision to love another person and the commitment to maintain that love. This component implies maintaining the relationship in good times and bad times

Question
Can anyone please help me with answering this question? : An accelerating (speeding up) body has a Net Force acting in the direction of motion. True or False? Why? ​
Solution 1
That's true.

Netwon's second law states that the resultant of the forces F acting on a body is equal to the product between its mass m and its acceleration a:
\sum F = ma
This means that if the net force acting on an object is different from zero (term on the left), than the acceleration of the object (term on the right) must be different from zero as well, and therefore the body is accelerating.

In particular, both F and a in the equation are vectors: this means that if the acceleration is positive, F and a have the same direction. In this problem, the acceleration is positive (because the object is speeding up), therefore the force and the acceleration have same direction.
Question
In a wave, what do you call the difference from crest to crest or trough to trough amplitude crest frequency wavelength
Solution 1
The correct answer is "wavelength".

In fact, this is exactly the definition of wavelength: in a wave, the wavelength is defined as the distance between two succesive crests or two successive troughs, therefore the correct answer is 
D) wavelength.
Question
The mechanical advantage of a machine is always greater than 1. TRUE OR FALSE
Solution 1

Answer: False

Explanation:

The Mechanical Advantage (M_{A}) of a machine is an adimensional quantity defined as the ratio of the output force F_{out}and the input force F_{in}:

M_{A}=\frac{F_{out}}{F_{in}}

It is important to note that M_{A} can be equal to 1, greater than 1 or less than 1:

-When F_{out} = F_{in},  M_{A}=1

-When F_{out} > F_{in},  M_{A}>1 This type of machines make task easiers

-When F_{out} < F_{in},  M_{A}

Question
A cran uses an average force of 5200N to lift a steel beam 25m. How much work does the crane do on the steal beam. Please help or explain how to do this anyone. Please and thank youu
Solution 1
The work done by a force is  given by:
W=Fd \cos \theta
where
F is the magnitude of the force
d is the distance covered by the object
\theta is the angle between the direction of the force and the direction of motion

In our problem, F=5200 Nd=25 m and \theta=0 (because the force is parallel to the direction of motion), so the work done by the crane is
W=(5200 N)(25 m)(\cos 0^{\circ})=1.3 \cdot 10^5 J
Question
Which statement best compares the accelerations of two objects in free fall?
Solution 1

Hello. This question is incomplete. The full question is:

"Which statement best compares the accelerations of two objects in free fall?  1.The heavier object has a greater acceleration. 2.The object that has the greater surface area has the lower acceleration 3. The object that has the smaller mass has the greater acceleration 4.The objects have the same acceleration "

Answer:

The objects have the same acceleration.

Explanation:

The free fall movement was studied by the Italian physicist Galileo Galilei. According to his studies, Galileo showed that bodies in free fall, even those of different masses, would reach the ground at the same time, as they would be subject to the same acceleration. The free fall is, therefore, a movement described by the bodies, abandoned at a certain height, which happens exclusively by the effect of local gravity. In this type of movement, we disregard the effect of drag or friction forces.

Solution 2
b.the object that has the greater surface area has the lower acceleration.

Question
PLEASE HELP!!!! 15 point!!!!! Scientist tested the effect of a fertilizer on the growth of plants. They had two sets of plants Group A which gets fertilizer water & and Group B which gets only water and sun (but equal amounts to Group A) 1. Explain how this scenario is a controlled experiment and identify the manipulated variable? 2. If the scientist only performed one experiment but it supported their hypothesis why can it not be considered a theory?
Solution 1
ANSWER 1: The manipulated variable is the fertilizer since the other factors (water and sunlight) are given in equal amounts. It is a controlled experiment because one group receives fertilizer while the other does not. Any differences in growth should be due to either having fertilizer or not.

ANSWER 2: In order for it to be a theory, it has to be tested numerous times by multiple scientists.

Hope it helps. God bless
Solution 2
2_ it doesn't because scientist have to do multiple tests and they have to get the same results

Question
An object is located 51 millimeters from a diverging lens. The object has a height of 13 millimeters and the image height is 3.5 millimeters. How far in front of the lens is the image located? A.51 millimeters B.1.12 millimeters C.13.7 millimeters D.189 millimeters
Solution 1
You would get 13.7 
lets say mi/mo= hi/ho
mi/51mm=3.5mm/13mm
by solving it you will C.13.7mm

hope this helps 
 
Solution 2
When the distance is divided by the height of an object is a constant. Therefore (x/3.5=51/13) yields the answer as 13.7.
