DanielleElmas [232]

Answer:

8 glasses

Step-by-step explanation:

Total volume : 1500 ml

Glasses capacity : 180 ml

Glasses can be filled : 1500 / 180 = 8.33

Notice it says completely fill thus it is 8 glasses

A clock is constructed so that it keeps perfect time when its simple pendulum has a period of 1.000 s at locations where g 5 9.8

mafiozo [28]

Answer

Given,

Period of the Pendulum, T= 1 s

acceleration due to gravity, g = 9.8 m/s²

Length of Bob = 0.2482 m

Loss of time in the clock = 1.5 minutes/ day

Loss of time in 1 oscillation

= $\dfrac{1.5\times 60}{24\times 60\times 60}$

= 0.001042

Hence, time period, T = 1 + 0.001042

T = 1.001042 s

a) Using Time period of oscillation formula

$T = 2\pi \sqrt{\dfrac{L}{g}}$

$1.001402 = 2\pi \sqrt{\dfrac{0.2482}{g'}}$

$g' = 9.77\ m/s^2$

Free fall acceleration at the clock location = 9.77 m/s²

b) Length of pendulum bob to keep it perfect time

$1 = 2\pi \sqrt{\dfrac{L}{g}}$

$1 = 2\pi \sqrt{\dfrac{L'}{9.77}}$

$L' = 0.2475\ m$

Hence, Length of pendulum bob is equal to 0.2475 m.

What is the length of x in the diagram below?

luda_lava [24]

Answer:

That is a 45-45-90 triangle next to a 30-60-90 triangle.

So, the height of the left triangle equals 5.

That makes the short side of the 30-60-90 triangle also equal to 5.

In a 30-60-90 triangle, the hypotenuse (or "x") is exactly twice the length of the shortest side.

Therefore, the hypotenuse (or "x") equals 10.
