Like a seesaw, it shows that the forces aren’t equal because if it was the seesaw would stay put

Much of the information taught in Earth-Space Science would not be available if it weren’t for our remote sensing abilities. Exp

boyakko [2]

Answer:

collecting information
imaging

Explanation:

Remote sensing means we do not have to be physically present in that particular area that we're studying by taking certain measurements. Several tools have been developed overtime to enable us to make this feat possible. Satellites in orbit have a major role to play in this regard. They exist to gather information from outer space and captures images that help us know more about our universe.

Hope that answers the question, have a great day!

What was his average swimming speed during the second half of the race if he tied the record, which was at an average speed of 2

Nimfa-mama [501]

I believe this question has additional detail which stated that during the 1st half, his speed was 2.01 m/s. From this we can calculate his speed during the second half, v2, using the formula:

v_ave = (v1 + v2) / 2

2.05 m/s = (2.01 m/s + v2) / 2

v2 = 2.09 m/s

How can you increase the torque you are putting on a lever, without exerting any more force?

Mariana [72]

Answer:

See below

Explanation:

Torgue = f * distance basically ...so if you want to increase torque with same f then the distance ( lever arm) must be increased

Two friends, Joe and Sam, go to the gym together to strength train. They decide to start off with an exercise called flat bench

astra-53 [7]

Answer:

216.31 (the work done by gravity is -216.31) positive for going up.

Explanation:

We look at this question first by getting the right equation for work.

Which should be... W = F x D.

From this, we can do everything, we need the Force (F) first - the question tells us that Joe is lying on his back and moves his arms upward to raise the barbell. This means that he is countering the force of graving on the object.

What is the formula for the force of gravity on an object near the earth?

Right here --- $F_{grav}$ = mg

m = the mass and...

g = the acceleration due to gravity which is 9.81 m/s2

Before we plug things in though, we need to convert everything to SI units,

the weight is in kg - so we're good to go there, but the length of Joe's arms are in "cm" we need m or meters. Converting 70 cm to m = .7 m.

Now, we just put it all together - (31.5kg)(9.81m/s2)(.7m) = 216.31 J or 216.31 N m.
