The vector values are '21 kilometers north' and '1 cm in the positive c-direction'.
Given:
The following values:
- Increase of 19 Kelvin
- 21 kilometers north
- 1 cm in the positive c-direction
- 11.5 mm
- 74°C
- 4 meters
To find:
The vector values from the given values.
Solution:
The vector quantities are those quantities with magnitude and direction.
Scalar quantities are those quantities with only magnitude and no direction.
- Increase of 19 Kelvins: Only a magnitude no direction, scalar quantity.
- 21 kilometers north: Magnitude and the direction, vector quantity.
- 1 cm in the positive c-direction: Magnitude, and the direction, vector quantity.
- 11.5 mm: Only a magnitude no direction, scalar quantity.
- O 74°C: Only a magnitude no direction, scalar quantity.
- 4 meters: Only a magnitude no direction, scalar quantity.
The vector values are '21 kilometers north' and '1 cm in the positive c-direction'.

Answer:
15,00kg
Explanation:
here's your solution
=> force = 45,000N
=> acceleration = 30m/s^2
=> mass = ?
=> Mass = force/acceleration
=> mass = 45,000/30
=> mass = 15,00kg
hope it helps
Answer:
A. 16 J
B. 16 J
C. 8 N
Explanation:
A. Determination of the kinetic energy.
Mass (m) = 0.5 Kg
Velocity (v) =. 8 m/s
Kinetic energy (KE) =?
KE = ½mv²
KE = ½ × 0.5 × 8²
KE = ½ × 0.5 × 64
KE = 0.5 × 32
KE = 16 J
B. Determination of the Workdone by the force.
Kinetic energy (KE) = 16 J
Workdone =.?
Workdone and kinetic energy has the same unit of measurement. Thus,
Workdone = kinetic energy
Workdone = 16 J
C. Determination of the force.
Workdone (Wd) = 16 J
Displacement (s) = 2 m
Force (F) =?
Wd = F × s
16 = F × 2
Divide both side by 2
F = 16 / 2
F = 8 N
