Answer:

Speed

Explanation:

- A scalar quantity is defined as a quantity which has a magnitude only (no direction)

- A vector quantity is defined as a quantity which has both a magnitude and a direction

Let's analyze each option:

- Centripetal force: force is a vector, because it has a magnitude and also a direction

- Weight: weight is a force, and force are vector quantities, so weight is a vector as well

- Speed: speed is a scalar quantity, because it has only a magnitude, no direction

- Acceleration: acceleration is a vector quantity, because it has a magnitude, but also a direction (because it represents the rate of charge in velocity, and since velocity is a vector, acceleration must be a vector as well)

So, the correct choice is

Speed

Scalar is a quantity such as mass or length that is completely determined by its own magnitude and has no direction. Therefore, your answer is Speed.

The law of suggests that the orbit of planets is not circular but .
SVEN [57.7K]
One of Kepler's laws is that the orbits of planets are elliptical. It's not a suggestion. BTW, circles are ellipses too, but so special that their likelihood is close to zero.

The potential energy of a catapult was completely converted into kinetic energy by releasing a small stone with a mass of 20 gra
DerKrebs [107]

1,000 grams = 1 kilogram
20 grams = 0.02 kilogram

Kinetic energy = (1/2) (mass) x (speed)²

                           (1/2) (0.02) x (15)² =

                                 (0.01)  x  (225)  =  2.25 joules

If a closed series circuit has a voltage of 12 V and R1 = 4 Ω and R2 = 2 Ω, what is the current running through R1 and R2?
Phantasy [73]
Total resistance=R1+ R2= 6Ω
Voltage=12v
Current =\frac{voltage}{resistance}
Current= 2A
In a series circuit, equal current passes through every resistance.

The following equation is an example of decay?<br><br> 232/90 TH---4/2 HE +228/88 RA?
DaniilM [7]

Answer:

Alpha decay

Explanation:

  • Alpha decay is one of the three major types of decays, others being, beta decay and gamma decay.
  • <em><u>When a radioactive isotope undergoes alpha decay it emits alpha particles. An alpha particle is equivalent to the nucleus of Helium atom.</u></em>
  • <em><u>Therefore, an atom undergoing decay, its atomic mass is decreased by 4 and its atomic number is decreased by 2. </u></em>
  • Thus, since 232/90 Th, has undergone alpha decay its mass number is reduced by 4 to 228 and its atomic number by 2 to 88, and becomes 228/88 Ra.
