The gravity.
In fact, the gravity will "pull" the bullet towards the ground, and the magnitude of the force is equal to the weight of the bullet:
where
m is the mass of the bullet
is the acceleration of gravity
Due to the presence of this force, the bullet will have a parabolic motion, which consists of two independent motions on the horizontal axis and on the vertical axis:
- on the horizontal axis, the bullet moves by uniform motion with constant speed
- on the vertical axis, the bullet moves by uniformly accelerated motion, with constant acceleration g towards the ground.
From that list, the <em>exponents</em> should be handled first.
Here's the memory device for the order of operations
that I often see here on Brainly. I didn't learn it this way,
but this is a good and handy thing to remember:
<em>P E M D A S</em>
It stands for the order in which operations should be performed
if you're working to simplify an expression that has several different
operations in it.
<em>P</em>arentheses
<em>E</em>xponents
<em>M</em>ultiplication
<em>D</em>ivision
<em>A</em>ddition
<em>S</em>ubtraction
Answer:
The answer to the very last one is: Boyle's law. Pressure and volume are inversely proportional as the new variable changes from the known. Pressure doubled equals 1/2 of original volume, assuming temperature remains the same. So 40.0 mL is the new volume as it is compressed.
The acceleration due to gravity at the Earth's surface is 9.8 m/s/s
<span>So a 2 kg object will accelerate at 9.8 m/s/s if it is dropped..... actually all dropped objects will accelerate at the same rate. </span>
<span>The force of gravity on the object is given by Newton's 2nd Law </span>
<span>F = m . a </span>
<span>F = 2 . 9.8 = 19.6 N </span>
<span>Now go to Mars , with a lower gravitational field strength. It only accelerates falling objects at 3.71 m/s/s </span>
<span>So the force of gravity on the object is F = 2 . 3.71 = 7.42 N </span>
<span>But the answer is (2) 2 kg, because the mass of the object stays the same and that is what you are asked for. </span>
<span>Someone was trying to be tricky.</span>
I think it B too it the one that make more Sense.
