The Hubble Space Telescope is a joint ESA/NASA project and was launched in 1990 by the Space Shuttle mission STS-31 into a low-Earth orbit 569 km above the ground. During its lifetime Hubble has become one of the most important science projects ever. Hope this helps! ~ Autumn :)

How do you know that forces are balanced when static friction acts on an object?

lyudmila [28]

By looking at the acceleration of the object.
In fact, Netwon's second law states that the resultant of the forces acting on an object is equal to the product between the mass m of the object and its acceleration:
$\sum F = ma$

So, when static friction is acting on the object, if the object is still not moving we know that all the forces are balanced: in fact, since the object is stationary, its acceleration is zero, and so the resultant of the forces (left term in the formula) must be zero as well (i.e. the forces are balanced).

16 grams of ice at –32°C is to be changed to steam at 172°C. The entire process requires _____ cal. Round your answer to the nea

inysia [295]

Answer:12,352 cal

Explanation:

Given

to change 16 gm ice at $-32^{\circ}C to 172^{\circ}C$

First we need to take ice to $0^{\circ}C$ then change its state to water and then raises water temperature from 0 to $100^{\circ}C$ .

After it change water phase to steam and then raise its temperature to $172^{\circ}C$

$heat required(Q)=16\times 0.5\times \left ( 0+32\right )$ + $16\times 80+16\times 1\times \left ( 100-0\right )+16\times 540+16\times 0.5\times \left ( 172-100\right )$

Q=12,352 cal
