The slope of the lines represent the runners' speeds. Therefore, the purple line represents Jerry, since he started off faster but also stopped in the middle, and the slope became 0 (horizontal portion of the line.)
The red one represents Katja because she started and ended at a constant pace, which is visible in the red line's constant slope.
The mass of the toddler is 12.5 kg.
Step-by-step explanation:
The equation for gravitational potential energy is Ep=mgh where;
Ep=gravitational potential energy
m=mass of an object
g=gravitational field strength
h=height in meters
Given that ; h= 1.5m, Ep=187.5J , g=10 N/kg then finding m;
Ep=mgh
187.5=m*10*1.5
187.5=15m
187.5/15 =15m/15
12.5 kg=m

Answer:
220 N * m or 220 J
Step-by-step explanation:
We have that the work formula would be the applied force multiplied by the distance traveled, that is:
W = F * d
In this case the F is 200 N and the distance is 1.1 meters, therefore we replace:
W = 200 * 1.1
W = 220 N * m = 220 J
Therefore the work carried out by Clarissa and her mom is 200 joules.
Answer:
Option b. 12 teaspoons.
Step-by-step explanation:
In the question it given :
1 cup = 16 tablespoons
1 tablespoon = 3 teaspoons
16 tablespoon = 48 teaspoons or 1 cup
A recipe calls for 1/4 cup of broth. Tabitha has only a teaspoon to measure broth.
1 cup broth = 48 teaspoons
1/4 cup broth = 48 ×
= 12 teaspoons
Tabitha should use 12 teaspoons of broth.
Answer:
600 times .012=7.20
7.20 times 6= 43.20
43.20+ 600= 643.20
the correct answer is b- $643.20
