A race car starts from a rest to increases its speed to 23 m/s over a distance of 120 m. Calculate acceleration.

Physics
1 answer:
Orlov [11]3 years ago
6 0

Answer:

Acceleration=115m/s²

Explanation:

speed=distance/time

23=120/time

/120 on both sides

0.2s is time

acceleration= change in velocity/time taken

23/0.2=115

acceleration=115m/s²

kumpel [21]

Answer:

m = \frac{k}{g} x,

graph of x vs m

Explanation:

For this exercise, the simplest way to determine the mass of the cylinder is to take a spring and hang the mass, measure how much the spring has stretched and calculate the mass, using the translational equilibrium equation

              F_e -W = 0

              k x = m g

              m = \frac{k}{g} x

We are assuming that you know the constant k of the spring, if it is not known you must carry out a previous step, calibrate the spring, for this a series of known masses are taken and hung by measuring the elongation (x) from the equilibrium position, with these data a graph of x vs m is made to serve as a spring calibration.

  In the latter case, the elongation measured with the cylinder is found on the graph and the corresponding ordinate is the mass

Dimas [21]

Answer: the capacity to understand the world, think rationally, and use resources effectively.

Explanation:

Intelligence refers to higher level abilities, the ability to learn, being creative, having an emotional knowledge, and ability to adapt to different scenarios.

Since Ashley, a psychology major, remarks that she has become interested in the study of intelligence, then Ashley is interested in the capacity to understand the world, think rationally, and use resources effectively.

Where does matter come from?
Pie
The Big Bang theory is matter and energy in the universe exploded out from one point. As the explosion occurred, energy and matter spread outward and formed the universe. The matter from the Big Bang formed clouds of gas.

A system expands from a volume of 1.00 l to 2.00 l against a constant external pressure of 1.00 atm. what is the work (w) done b
stepan [7]
The work done by a system kept at constant pressure is given by:
W=p \Delta V = p (V_f - V_i)
where
p is the pressure
V_f is the final volume
V_i is the initial volume

If we plug the numbers given by the problem into this equation, we find
W=p (V_f -V_i)=(1.00 atm)(2.00 L-1.00 L)=1.00 L\cdot atm

And since 1 atm \cdot L = 101.3 J, we have that the work done is
W= 1.00 atm \cdot L = 101.3 J

RoseWind [281]

Answer:

<h2>1 st statement is correct </h2>

Explanation:

The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside
