1. To obtain the volume of a regular-shaped cube, we simply use the formula.

2. To find the volume of an irregular shaped object, we simply use displace method

<h3>Volume of regular shape cube</h3>

The volume of a cube can be obtained by using the formula below:

Volume = Length × Width × Height

<h3>Volume of irregular object</h3>

The volume of irregular objects can be obtained by using displacement method as illustrated below:

  • Volume of water = 20 mL
  • Volume of water + stone = 25 mL
  • Volume of stone =?

Volume of stone = (Volume of water + stone) - (volume of water)

Volume of stone = 25 - 20

Volume of stone = 5 mL

Thus, we can see that the volume of regular objects can be obtained by using their formulas whereas, the volume of irregular objects can be obtained by using displacement method.

A mass hangs on the end of a massless rope. The pendulum is held horizontal and released from rest. When the mass reaches the bo
drek231 [11]

Answer:

T = 37.5 N

Explanation:

As the pendulum reached to the lowest position then we will have

T - mg = \frac{mv^2}{L}

14.2 - m(9.81) = \frac{m(2.9^2)}{L}

now when it will reach to the height of the peg then its speed is given as

v_f^2 - v_i^2 = 2 a d

so we will have

v_f^2 - 2.9^2 = 2(-9.81)(\frac{L}{5})

v_f^2 = 2.9^2 - 3.924L

also we know that

2.9^2 - 0 = 2(9.81)(L)

L = 0.43 m

m = 0.48 kg

now we have speed of the pendulum when it reach the same height is given as

v_f^2 = 2.9^2 - (3.924(0.43)

v_f = 2.6 m/s

Now the tension in the string is given as

T = \frac{mv_f^2}{\frac{L}{5}}

T = \frac{0.48(2.6)^2}{\frac{0.43}{5}}

T = 37.5 N

John runs for 10 mins at a uniform speed 9kn/h. At what speed should he run for the next 20mins so that theaverage speed comes t
kolbaska11 [484]

Answer:

13.5 km/h

Explanation:

John runs for 10 min at 9 km/h, then 20 min at v.  He will have run a total of 30 min at 12 km/h.

Therefore:

(30 min) (12 km/h) = (10 min) (9 km/h) + (20 min) v

v = 13.5 km/h
