Answer:
Velocity of the 24.6 g marble is 31 cm/s.
Step-by-step explanation:
Given:
Marble 1:
Mass of the marble = 12.3 gm
Velocity of before collision = 15.5 cm/s
Velocity of after collision = 77.5 cm/s
Marble 2:
Mass of the marble = 24.6 gm
Velocity of before collision = 62 cm/s
Velocity of after collision = ?
From the law of conservation of momentum, we know that momentum before equals the momentum after :
So,
⇒
⇒
⇒ Plugging the values.
⇒
⇒
⇒
⇒ ...subtracting both sides 953.25
⇒
⇒ ...dividing both sides with 24.6
⇒
⇒ cm/s
The velocity of the 24.6 g marble after the collision is 31 cm/s and it will move opposite to of the 12.3 g marbles that is towards left.
0.5 will be rounded to 1.0
1.2 will be rounded to 1.0
1.7 will be rounded to 2.0
3.4 will be rounded to 3.0
Answer:
263.76
Step-by-step explanation:
Assuming the shaded area is the yellow area all we must do is find the area of the small circle and subtract it from the larger circle.
To do this we can use the area of a circle equation:
first we need to find the radius of the large circle which is simply 4+6= 10
so the area would be:
then we find the area of the small circle is
next we evaluate:
Then replace pi with 3.14:
84 · 3.14 = 263.76
And you have your answer!

Answer:

Step-by-step explanation:
*Perpendicular lines always have the opposite slope (meaning that you have to switch the numerator and denominator) and sign when comparing to the given equation.
To start off, convert the equation to be formatted into y=. You do this by first subtracting the 3x from both sides of the equation so that it now reads . Now, divide the whole equation by three in order to get rid of the value attached to the y. The equation should now read to be: . Now, just switch the the slope into its opposite (which is the reciprocal) and switch the negative sign into a positive.
