Lien uses a spring scale to pull a block toward the right across the lab table. The scale reads 8 N. Which force should Lien conclude is also 8 N?

Answers

Answer

The force on the left across the lab table.

Explanation

The Newton's third law of motion states that; action and reaction are equal but a ct in opposite direction.

When the block of is pulled on the right with a force of X Newtons then there is a force -X Newtons applying and equal force on the left. For every action there must be a reaction with is equal and applying in the opposite direction.

So, if the block is pulled on the right by a force of 8 N there is another equal force applying on the left.


The force to the left of the block on the spring scale

NASA decides to put a 128 kg satellite into orbit over the planet Venus because they want to take pictures. The satellite is 37,000,000 m above the surface of venus. Calculate the gravitational field at that altitude. m/s2
how do you calculate this

Answers

1).  Look up the acceleration of gravity on the surface of Venus.  It's 8.87 m/s².
(That's about 10% less than on Earth.)

2).  Look up the radius of Venus.  It's 6051.8 km.  
(That's about 5% less than Earth's.)

3).  Remember that the gravitational field (acceleration, force) changes
opposite to the square of the distance from the planet ... or the distance
between any two masses that are gravitating.

Now we have enough information to do the calculating.  Notice that the question
only asks for the planet's "gravitational field" (acceleration) way out there.  That
has nothing to do with the satellite's mass, or whatever you decide to put out there,
or even if there's nothing out there at all.  It's just a characteristic of Venus at that
distance from it.

The distances we need to compare are the distances from the center of Venus.

On the surface (distance from the center is the radius of Venus), it's 6,051,800 m.
In the orbit, it's 37,000,000 m.

The ratio is (37,000,000 / 6,051,800) = about 6.1 .

The gravity way out in the orbit is less than on the surface, and by the
same amount as the square of the distance ratio.

Surface gravity = 8.87

Gravity out at the orbit = 8.87 divided by (the distance ratio)²

Gravity = 8.87 / (6.1)²

Better way:  Gravity = 8.87 x (6,051,800/37,000,000)² = 0.2373 m/sec²

What is the minimum resistance which can be made using five resistors each of 1/5

Answers

The minimum resistance to the flow of electrical current is achieved when
the resistors are connected in parallel, just as the minimum resistance to the
flow of vehicular traffic is achieved when several lanes are built in parallel.

When 5 equal resistors are connected in parallel, the net resistance of their
combination is just 1/5 of the value of each one. 

So 5 equal resistors in parallel, each with a resistance of 1/5 ohm, have a
combined net resistance 0f 1/25 ohm.
