This is a good example of unit conversion. Look at the units you have and the units you need to solve for.

In #1 you’re given weight in units N and area in units cm². You want to find pressure in units Pa (pascals) which is force/area, or N/m². So you just divide the force given by the area given, but be careful because the area is given in cm², whereas pressure is in m². Before you calculate pressure, make sure you convert 324cm² into m²

Savannah drove 716 miles on Monday. She drove another 572 miles on Tuesday. About how many miles did she drive
Korolek [52]

Explanation:

We have,

Savannah drove 716 miles on Monday and She drove another 572 miles on Tuesday.

It is required to find the total distance covered by her altogether. It is equal to the sum of distance covered on Monday and distance covered on Tuesday. So,

d = 716 miles + 572 miles

d = 1288 miles

So, she drive 1288 miles altogether.

Two children stand on a platform at the top of a curving slide next to a backyard swimming pool. At the same moment the smaller
IgorC [24]

Answer:

Explanation:

i )

In a conservative field like gravitational field , loss of potential energy  or work done , depends upon the initial and final point and not the manner in which 2 nd point has been reached . Since the initial and final point is same in both the cases of straight and curved path , final velocity will remain same for both of them .

Hence , due to increased mass of larger child , his kinetic energy will be greater .

ii ) Since the initial and final point is same in both the cases of straight and curved path , final velocity will remain same for both of them .

iii ) Smaller child undergo free fall , therefore , he will fall with acceleration g . The larger child falls on curved path . So , he will have only a component of

vertical g at any moment  . hence average acceleration  will be less.
