Answer:

gravitational potential energy

The main types of used energy that are used in a football are kinetic energy and heat energy. So when the quarterback is about to throw the football, or the kicker is about to kick the football, there is 100% of gravitational potential energy.

The Hubble Space Telescope orbits 600 km above Earth's surface. Earth's radius is about 6370 km. Use the Pythagorean Theorem to

musickatia [10]

To solve this problem we will apply the concept given by Pythagoras in the description of the lengths of the legs of a rectangular triangle and if equality against the square of the hypotenuse, that is

$a^2+b^2=c^2$

Here,

a, b = Legs of a triangle

c = Hypotenuse

According to the attached chart then we would have to

$a=x\\b = 6370km\\c = 600+6370km = 6970km$

Substituting the given the lengths into the Pythagorean Theorem.

$a^2+b^2 = c^2 \\x^2 +(6370)^2 = (6970)^2\\x = 2829.13km \approx 2830km$

Therefore the distance x is 2830km.

Which is the correct product of the significant figures 3278 and 42?

Svetradugi [14.3K]

Answer:

$1.4\cdot 10^5$

Explanation:

In multiplications or divisions, the result must be written using a number of significant figures equal to the smallest number of significant figures contained in the original numbers.

For instance, in this case the two numbers are:

3278 --> 4 significant figures

42 --> 2 significant figures

So, the product must be written using 2 significant figures.

Calculating the product, we get:

$3278\cdot 42=137676$

Therefore, using 2 significant figures only, the result is

$1.4\cdot 10^5$

A car has a mass of 1200 kg. A man can comfortably push down with a force of 400 N. If the small piston in a hydraulic jack has

kotegsom [21]

A) F1/A1=F2/A2
F2 = 12000 Newtons, while F1 = 400 Newtons and area A1= 6 cm²
400/6 = 12000/A2
A2 = (6 × 12000)/400
= 180 cm²

b) How long does this lift the car
d2 =F1/F2×d1
= (400/12000)× 20
= (1/30)×20
= 20/30
= 0.67 cm
This lifts the car a distance of 0.67 cm
