The earnings of movie in its opening weekend = 114000000$

We have

       1 kilo = 10^3

       1 Mega = 10^6

       1 Giga = 10^9

       1 Tera = 10^{12}

       1 Peta = 10^{15}

       1 Exa = 10^{18}

       1 Zetta = 10^{21}

       1 Yotta = 10^{24}

a) We have 1 Giga = 10^9 and earnings of movie in its opening weekend = 114000000$

Earnings = 0.114*10^9 $ =0.114 Giga dollars

b) We have 1 Tera = 10^{12} and earnings of movie in its opening weekend = 114000000$

Earnings = 0.000114*10^{12}$ =0.000114 Tera dollars

A 50-g chunk of 80 degrees C iron is dropped into a cavity in a very large block of ice at 0 degrees C. Show that 5.5 g of ice w
Alenkasestr [34]

Answer:

5.5g of ice melts when a 50g chunk of iron at 80°C is dropped into a cavity

Explanation:

The concept to solve this problem is given by Energy Transferred, the equation is given by,

Q = mc\Delta T

Where,

Q= Energy transferred

m = mass of water

c = specific heat capacity

\Delta T = Temperature change (K or °C)

Replacing the values where mass is 50g and temperature is 80°C to 0°C we have,

Q = mc\Delta T

Q = 50*0.11*(80-0)

Q = 440cal

Then we can calculate the heat absorbed by m grams of ice at 0°C, then

Q_2 = mL = 80*m

How Q_1=Q_2, so

80m=440

m=\frac{440}{80}

m = 5.5g

Then 5.5g of ice melts when a 50g chunk of iron at 80°C is dropped into a cavity

Mike walks 200 km in 6 hours.he then walks another 100km in 4 hours .what is his average speed?
kolbaska11 [484]

Average speed is defined as the ratio of total distance covered in total given time

speed = \frac{distance}{time}

here we know that total distance that man moved is

d_1 = 200 km

d_2 = 100 km

so total distance is

d = d_1 + d_2

d = 200 km + 100 km

d = 300 km

now here total time of the motion is

t_1 = 6 hours

t_2 = 4 hours

total time will be given as

t = t_1 + t_2

t = 6 + 4 = 10 hours

now by above formula

v_{avg} = \frac{300}{10}

v_{avg} = 30 km/h

so his average speed is 30 km/h

A student uses the right-hand rule as shown.
Kipish [7]

Answer:

right is the correct answer to the given question .

Explanation:

In this question figure is missing

The main objective right-hand rule to decide the position of the magnetic force on the positive force acting, either the position of the thumb of a right hand with in position of v, the fingers throughout the position of B1, and a right angles throughout the position of F1 to the hand positions.

So    F1 \ =\ q\ v \ B1\ Sin\alpha

  • So from the magnetic right hand rule the direction of the magnetic field in front of a wire is right .
  • All the others options are incorrect because they do not give the direction of the magnetic field in front of a wire is right .
