1.8x 10^4
This is 18000 expressed in scientific notation.
Answer:
A
Explanation:
I'm pretty sure it's A. That's the one that makes the most sense and checks out
Answer:
4.0 Kg
Explanation:
From the question given above, the following data were obtained:
Velocity (v) = 48 m/s
Kinetic energy (KE) = 4632 J
Mass (m) =?
Kinetic energy can be defined as the energy possess by a moving object. Mathematically, it is expressed as:
KE = ½mv²
Where
KE => kinetic energy
m => mass of object
v => velocity
With the above formula, we can obtain the mass of the object as follow:
Velocity (v) = 48 m/s
Kinetic energy (KE) = 4632 J
Mass (m) =?
KE = ½mv²
4632 = ½ × m × 48²
4632 = ½ × m × 2304
4632 = m × 1152
Divide both side by 1152
m = 4632 / 1152
m = 4.0 Kg
Therefore, the mass of the object is 4.0 Kg
Answer:Resultant force
Explanation:
The net given force is known as the resultant force. The resultant force is the single force that acts in place of other forces combined together.
