Answer:

option C

2450

Step-by-step explanation:

Given in the question that,

mass of Dina = 50kg

height at which Dina is standing = 5m

Formula to calculate potential energy

<h3>  PE = Mgh</h3>

where M = mass of the object

           g = acceleration due to gravity = 9.8 m/s²

           h = height

Plug values in the formula above

50(9.8)(5)

2450 joules

Answer:

C

Step-by-step explanation:

Formula for potential energy is PE = m*g*h

where

m is the mass, in kg

g is the acceleration due to gravity, in meters per second squared, and

h is the height, in meters

The problem gives m = 50, g = 9.8, and h = 5. We plug that into the formula and get out answer. So:

PE=mgh\\PE=(50)(9.8)(5)\\PE=2450

Correct answer is C.

It is recommended that an adult drink 64 fluid ounces of water everyday Josie has already consumed 700 mL of water how many more
katen-ka-za [31]

Answer:

1.2 litres  more water should Josie drink.

Step-by-step explanation:

As given

It is recommended that an adult drink 64 fluid ounces of water everyday .

As given

1 ounce = 0.0296 litre .

Now convert 64 ounces into litre.

64 ounce = 64 × 0.0296

                = 1.9 litres (Approx)

As

1 litre = 1000 ml

1\ ml= \frac{1}{1000}\ litre

Now convert 700 ml into litre.

700\ ml= \frac{700}{1000}\ litre

700\ ml= \frac{7}{10}\ litre

700 ml = 0 .7 litre

Thus

Recommended amount of water a adult should drink = Amount of water Josie already consumed + More water should Josie drink.

Putting the value

1.9 litres = 0 .7 litres +  More water should Josie drink.

More water should Josie drink = 1.9 - 0.7

More water should Josie drink = 1.2 litres .

Therefore 1.2 litres  more water should Josie drink.

Anni [7]

Answer:


Step-by-step explanation:

In mathematics, a curve (also called a curved line in older texts) is an object similar to a line but that need not be straight. Thus, a curve is a generalization of a line, in that its curvature need not be zero.

Find two numbers, if … b Their sum is −7 and their difference is 14
Delicious77 [7]

Answer:

x=0

y=-21/7

Step-by-step explanation:

Let the two unknown be x and y

x+y=-7...(1)

x-y=14...(2)

From (1) make x the subject of formula

x=-7-y...(3)

Substitute (3) into (2)

-7-y-y=14

-7-2y=14

Add 7 to both sides

-2y=21

Add both sides by-2

y=-21/2

Substitute the value of y into (3)

x=-7-(-21/2)

x=-7+21/3

Lcm

x=-21+21/3

x=0/3

x=0
