The volume of one rubber ball and the cost of producing one ball and the profit will it make on each ball will be 20.58 cm³, $0.09261, and $0.40739 respectively.

It is concerned with the geometry, region, and density of various 2D and 3D shapes.

The given data in the problem is;

r is the Rubber balls = 1.7 cm

V is the volume

C is the cost of production

P is the profit

The volume of the rubber ball is  found as;

[tex]\rm v= \frac{4}{3} \pi r^3 \\\\ \rm v= \frac{4}{3} \times 3.14 (4.913)^3 \\\\ \rm v= 20.58 cm^3[/tex]

If the price of the rubber required to make a ball is $0.0045/cm3, the ball's production cost will be $0.0045/cm3.

The cost of a ball is the multiplication of the cost of one ball and the selling price of the ball;

C = 0.0045 x 20.58

C = $0.09261

P is the profit gained and profit is the subtraction of the selling price and cost price.

P = S.P.-C.P.

P=0.5 - 0.09261

P = $0.40739

Hence the volume of one rubber ball and the cost of producing one ball and the profit will it make on each ball will be 20.58 cm³, $0.09261, and $0.40739 respectively.

Answer:

Explanation:

Answer:

Solution s =ut + ½ at 2 = 0×10 + ½ × 10×10 2 = 1000/2=500 m

Explanation:

The body is accelerating from stationary to a velocity of 100 m/s within 10 seconds. Thus, the distance covered is 500 m.

Acceleration of a moving body is the rate of change in its velocity. Acceleration is a vector quantity having both magnitude and direction. The change in magnitude or direction or both in velocity causes an acceleration in the moving body.

The relation between distance with the velocity, acceleration and time is given as :

s = ut + 1/2 at²

The initial velocity u = 0 here

v = 100 m/s

t = 10 seconds.

acceleration =  100 /10 = 10 m/s²

Then the distance covered is calculated as follows:

s = 1/2 at²

  = 1/2 10 m/s²× 10²

  = 500 m

Therefore, the distance covered by the body is 500 m.

Here; f = 450 rev/ min = 450/60 rev/s

f. = 15/2 rev/s

Therefore the angular velocity w. = 2π f•

= 15π rad / sec at t= 10s, w = 0

Therefore Angular acceleration

a=w-w./t

= w + 1/2 at^2

= 15π * 10 - 1/2 (3π/2) 10^2

= 150-75m = 75π rad

Therefore No. of revolution = •/2π = 75/ 2π

The probability that a randomly chosen nucleus in a radioactive sample will have decayed in a given time is  96.875%. The sample has experienced 5 half lives. The correct option is A.

Half life is the time required for the heavy nucleus or any radioactive material to disintegrate by half its quantity.

After one half life, the probability of decay of any nucleus is given by 50%. = 0.5

After two half lives gone,  probability of decay is 0.5 + 1/2(0.5) = 0.75

After, three half lives gone,  probability of decay is 0.5 + 1/2(0.5) + (1/2)²(0.5) = 0.875

After, four half lives gone,  probability of decay is 0.5 + 1/2(0.5) = 0.875 + (1/2)³(0.5) = 0.9375.

After, five half lives gone,  probability of decay is 0.9375 + (1/2)⁴(0.5) = 0.96875.

Thus, the sample has experienced 5 half lives. The correct option is A.\

Answer:The heat flows from an object at a higher temperature to the object at a lower temperature. Thus the option A is correct.

Explanation:What is heat flow?

The flow of heat is the transfer of heat that concerns its generation, use and conversion, and exchange.The heat flow follows the laws of the thermodynamics. Heat will flow from the body that is at a higher temperature and will move towards a body of a lower temperature. Thereby maintaining an equilibrium state. As energy is needed to warm or heat up the cold body there is an exchange of energy that takes place.

u = -18cm

Generally, the equation for magnification is mathematically given as

1/f = 1/v +1/u

therefore,

-1/30 = 1/v + 1/u

v = -2.5u

Hence,

-1/30 = -1/2.5u + 1/u
