Choices 1,3,4 are supported.
Choice 2 is incorrect because a horizontal slope on a position time graph means the object is starionary.
Choice 5 is incorrect because the speed of an individual can be determined by calculating the slope at a point on the position time graph.
Answer:
temperature
Explanation:
temperature change forms different elements and different element sustain different colour
Answer:
The person will travel 24 meters.
Explanation:
Distance = Rate * TIme
Distance = d = ?
Rate = r = 6 m/s
Time = t = 4 seconds
d = r*t = (6 m/s)*(4 seconds)
d = 24 m
**Note that the units (m/s) and (s/1) cancel to leave the answer in meters, the desired unit**
Answer:
R = 0.24 kilo-ohm
Explanation:
Given that,
Voltage, V = 12 volt
Current, I = 50 mA = 0.05 A
We need to find the resistance of the resistor. We can find it using Ohm's law. So,
V = IR
or
R = 0.24 kohm
So, the value of resistance is 0.24 kilo-ohm.
Answer:
C
Explanation:
25% is two half lives.
Each half life requires 5730 years.
So two half lives requires
2
