A 1.5-kg ball is throw at 10 m/s. What is the balls momentum?
alexdok [17]

Answer : The momentum of ball is, 15 kg.m/s

Explanation :

Momentum : It is defined as the motion of a moving body. Or it is defined as the product of mass of velocity of an object.

Formula of momentum is:

where,  

p = momentum  = ?

m = mass  = 1.5 kg

v = velocity = 10 m/s

Now put all the given values in the above formula, we get:

Therefore, the momentum of ball is 15 kg.m/s

Please someone helppp me.. I will mark as brainliest.​
Mademuasel [1]

Answer:

b) G.P.E = Mgh

300j = M x 10 m/s² x 15 m

300 j/ 10 m/s² x 15 m = M

300j/ 150 s² = M

2kg = M

c) K.E = 1/2 m v²

K.E = 1/2 (50) (50)²

K.E = 1/2 (50) (2500)

K.E= 125000/2

K.E = 625 000 J

In the manufacturing of computer chips, cylinders of silicon are cut into thin wafers that are 3.00 in. in diameter and have a m
Shalnov [3]

Answer: thickness h = 0.014cm

Question: In the manufacturing of computer chips, cylinders of silicon are cut into thin wafers that are 3.30 inches in diameter and have a mass of 1.50 g of silicon. How thick (mm) is each wafer if silicon has a density of 2.33 g/cm 3 ? (The volume of a cylinder is V=πr 2 h )

Explanation:

The volume of a cylinder is

Volume V = πr^2h ....1

The density of a material is

Density D = mass m / volume V

D = m/V ....2

Since m and D are given, we can make V the subject of formula.

V = m/D ....3

From equation 1, we need to derive the thickness h of the cylindrical silicon.

h = V/πr^2 .....4

Substituting equation 3 into 4

h = (m/D)/πr^2 .....5

Given.

mass m = 1.50g

density D = 2.33g/cm^3

radius r = diameter/2 = 3.00in/2 = 7.62/2 cm = 3.81cm

Substituting the given values into the equation

h = (1.5/2.33)/(π ×3.81^2)

thickness h = 0.014cm
