C.  If an object has a constant velocity, it covers equal distances over equal time intervals.

<h3>What is constant velocity?</h3>

Constant velocity is a type of velocity that results from a constant change in displacement over a given time interval.

To have a constant velocity, an object must have a constant speed in a constant direction.

This is what happens during a constant velocity motion,

v1 = v2

v2 - v1 = 0

where;

  • v1 is the initial velocity
  • v2 is the final velocity

During constant velocity, speed is constant. If speed is constant, distance traveled is proportional to change in time of motion.

Thus, if an object has a constant velocity, it covers equal distances over equal time intervals.

a car accelerates uniformly at from rest at a speed of 23.7 km/h in 6.5s. find the distance the car travels during this time
hodyreva [135]

speed = distance / time

 distance =speed × time

   d   = v × t

 d=   23.7 kmh⁻¹ ˣ 6.5 s

 d = 154.05 kmh⁻¹s.

Which is a vector quantity
Korolek [52]

Explanation:

Physical quantities are usually designated as either vector or scalar quantities.

There are several fundamental quantities know out there that makes definition of the world possible. Derived quantities are obtained from these fundamental quantities.

  • A vector quantity expresses a quantity that shows both magnitude and direction.
  • With a vector, you know the amount or quantity of measurement taken and the directional attribute.
  • A scalar quantity is a quantity that shows magnitude but no direction.
  • For example velocity is a vector and speed is a scalar. If a body moves at 10m/s due east, that is a vector.

What is the equivalent resistance between points A and C if R1=1430, R2=1350, R3=1100, R4=1350, and R5=1150.
Marianna [84]

R1 + R4 = 1430 + 1350 = 2780 = R14    series combination of R1 & R4

R2 + R5 = 1350 + 1150 = 2500 = R25

The circuit has been reduced to 3 resistors in parallel

R314 = 2780 * 1100 / (2780 + 1100) = 788  this is the resistance of the parallel combination of R14 and R3

R31425 = 2500 * 788 / (2500 + 788) = 599 which is the equivalent of the circuit  - you can also use the formula for 3 resistors in parallel but this seems simpler

2. Who bombarded molybdenum with atomic number (Z=42) with fast moving<br>neutrons?<br>​
Dominik [7]

Answer:

This question appears incomplete

Explanation:

This question appears incomplete, however Molybdenum-99 (⁹⁹Mo) is produced by bombarding Molybdenum-98 (⁹⁸Mo) with fast moving neutrons (¹₀n) as shown below

⁹⁸₄₂Mo + ¹₀n ⇒  ⁹⁹₄₂Mo + ⁰₀γ

This reaction is a nuclear caption reaction (which occurs in a nuclear reactor) for the production of Molybdenum-99 (⁹⁹Mo) which serves as a "precursor" for the production of medically viable/ Clinical Grade Technutium-99m (⁹⁹Tc) through Ion-exchange technique.

Fission and fusion reactions both involve making changes to an atom's _____.
spayn [35]

Option (A) is correct. Fission and fusion reactions both involve making changes to an atom's nuclei.

Nuclear fission is a process in which a bigger nucleus breaks into two or more smaller nuclei with the liberation of large amount of energy.

Nuclear fusion is a process in which two smaller nuclei fuse together to form a bigger nucleus. A tremendous amount of energy is released during fusion.

Thus both fission and fusion involve the changes in the nuclei of atoms. Rest of the atom like the electronic configuration etc remains same.
