Answer:

0.5 Amperes

Explanation:

Information that we have:

Power: P=60W

Voltage: V=120V

and we use the equation that relates this two quantities to the Current (I):

I=\frac{P}{V}

where I is the curent, P is the Power and V is the Voltage.

we substitute the values given for the Power and the Voltage to find the current:

I=\frac{60W}{120V}\\ I=0.5A

the Current running into the bulb is 0.5 Amperes

If F1 = 390 N and F2 = 550 N , determine the angle θ(0∘≤θ≤180∘) between them, so that the resultant force has a magnitude of FR
Nadya [2.5K]

Answer:

Explanation:

R² = F₁² + F₂² + 2F₁F₂ Cosθ , R is resultant force , θ is angle between them

780² = 390² + 550² + 2 x 390 x 550 Cosθ

608400 = 152100 + 302500 + 429000  Cosθ

Cosθ =  .3585

θ  = 69 degree.

anzhelika [568]
A number might be rounded when determining the number of people who will attend a basketball game. A number should not be rounded when determining the number of students who will participate in a chemistry lab. Only an estimate is needed for attendance at a basketball game because everyone will still get to see the game. In a chemistry lab the correct number of students should be known so that everybody has the proper equipment to use.

What will be the answer??
AnnZ [28]
5-a).  Acceleration is a vector defined as the rate of change of velocity.
Its magnitude has units of [length/time²].  The SI unit is meter/second².
Its direction is the direction in which velocity is increasing. 

5-b).  The graph says that the object's speed is not changing.
When we look at any time, from zero to almost 50 minutes, the
object's speed is the same . . . 60 m/s .  This will make it easy.

There are 60 seconds in a minute, so 30 minutes = 1,800 seconds.
In every one of those seconds, the object covered 60 meters.
It travelled a total of (60 m/s)·(1,800 s) = 108,000 meters (108 km) .

What determines what will be tested in a scientific experiment
Artyom0805 [142]
What you want to test and your hypothesis does.
For example, say you came up with a hypothesis that 'The higher the temperature, the higher the reaction rate will be'.
Your independent variable (the one you change) will be temperature. The dependent variable (the one that changes because of the independent) will be the reaction rate (e.g. bubbles produced).
