Answer:

The electric bill for June is Rs198000

Explanation:

Convert volt to watt, but in order to do so I need to know the amps and since it is not provided I converted if the amps was 1.

I multiple 50 with 10 then  with 30 so I know how much watt the fan takes at June.

Since there are 2 light bulb I multiple 10 with 2 than with 8 than with 30.

15000 watts for the fan,

4800 watts for light bulb,

add them and then times it by 10.

Rs198000

PLEASE HELP ASAP! THANKS!<br><br> Why is it a rare occasion to see a solar eclipse from your home?
Y_Kistochka [10]

Answer:

It is very rare to see a solar eclipse from your home, because the Earth, Sun, and the moon need to align just right.  Not everyone in the world can view a solar eclipse, only some area can.  A solar eclipse is where the moon blocks out the sun.  If you think about it:  Let's say you live in Florida, U.S.A.  You may see the moon coming in front of the sun, but if you lived in California or sumthin', the moon and the sun wouldn't be aligned to form a solar eclipse.  It all depends on location... so it is rare to see one.

A 0.145-kg baseball pitched horizontally at 35.0 m/s strikes a bat and is popped straight up to a height of 40.0m. If the contac
Nookie1986 [14]

Answer:

F = 2.6 \times 10^3 N

Explanation:

Maximum height reached by the ball after being popped by the bat is given as

y = 40 m

now we know by energy conservation final speed of the ball after being hit by the bat is given as

\frac{1}{2}mv^2 = mgh

v = \sqrt{2gh}

v = \sqrt{2(9.81)(40)}

v = 28 m/s

now the change in momentum of the ball is given as

\Delta P = m(v_f - v_i)

\Delta P = 0.145(28\hat j + 35 \hat i)

now force is given as rate of change in momentum

F = \frac{\Delta P}{\Delta t}

F = \frac{0.145(28\hat j + 35 \hat i)}{2.5 \times 10^{-3}}

F = (1.62 \hat j + 2.03 \hat i)\times 10^3 N

so magnitude of the force is given as

F = \sqrt{1.62^2 + 2.03^2} \times 10^3 N

F = 2.6 \times 10^3 N

Name the changes in the state of matter
olganol [36]
Liquid to gas phase transitions are known as "vaporization." Liquid to solid phase transitions are known as "freezing." Solid to liquid phase transitions are known as "melting." Solid to gas phase transitions are known as "sublimation." In most cases, solids turn into gases only after an intermediate liquid state.

hope this helps!!
