Answers
the diagram below shows different weights on the see-saw. Will the see-saw move?
Answers
Answer:
yes it will
Explanation:
As the net torque on the see-saw is not equal to zero, the see-saw in the given diagram will move.
What is torque?The force that can cause an object to rotate along an axis is measured as torque. In linear kinematics, force is what drives an object's acceleration. Similar to this, an angular acceleration is brought on by torque.
As a result, torque can be thought of as the rotational counterpart to force. Torque is referred to using a variety of terms, including moment and moment of force. The moment arm or lever arm is the measurement of the separation between the point of application of force and the axis of rotation.
The net torque on the see-saw = 3 N × 1.20m - 8 N × 0.50 m
= - 0.4 N-m.
As the net torque on the see-saw is not equal to zero, the see-saw move will move.

Byron measured the mass of a bag of cookies that he bought at the store and found that they were 45 grams. He set the cookies on the counter, but his little brother found them. His brother could not get the bag open so he smashed them to little pieces. What could Byron expect to find when he measured the mass of the cookies again?
Group of answer choices
They would be more than 45 grams since there are more pieces.
They would be 45 grams since they have the same mass.
They would be less than 45 grams since they were in little pieces.
The mass of the cookies would been reduced by 5 grams.

Calculate the pressure exerted by mercury column of 76cm high at its bottom. Given that the density of mercury is 13600kg/m³ and g=9.8 m/s².
Answers
Answer:
P = 101292.8
Explanation:
Use
Pressure p = H D g
H = height ( in metric)
D = density ( in metric )
g = gravity
So
H = 76 cm = 0.76 m
D = 13600 kg/m3
And g = 9.8
P = HDg
= 0.76× 13600×9.8
= 101292.8 pascal
Or = 1.012928 × 10^5

In the middle of a thunderstorm, a lightning bolt flashes. It takes Roberto 5 seconds to
hear the thunder afterwards. How far is the source of lightning from Roberto? The temperature is 22° C.
Speed of sound at 22°C = ?
d = ?
You will be reported if you didn't answer properly
Answers
Answer:
v = 344.1 m / s
d = 1720.5 m
Explanation:
For this problem we must calculate the speed of sound in air at 22ºC
v = 331 RA (1+ T / 273)
we calculate
v = 331 RA (1 + 22/273)
v = 344.1 m / s
the speed of the wave is constant,
v = d / t
d = v t
we calculate
d = 344.1 5
d = 1720.5 m

This is due today and I’m confused on this question
Answers
Answer: 5.4 kg
Explanation:"Recall that force is the result when we multiply the values of an object's mass and acceleration. Mathematically, we have
F = ma
where F is the force (in Newtons, N), m is the mass (in kilograms, kg), and a is the acceleration (in m/s²).
Since we know that the eagle was accelerating at 22.35 m/s² with a force of 120N, we can solve for the eagle's mass as shown below.
m = F/a
m = (120)/(22.35) ≈ 5.4 kg
Hence, the eagle has a mass of approximately 5.4 kg."

A pitcher throws a 145 g baseball at a velocity of 30.00 m/s. How much kinetic energy does the ball have?
Answers
Final Answer:
65.25 J is the kinetic energy that the ball has.
Explanation:
M = 145g
(Reminder: kg must be used in this formula, thus we need to convert 145g to kg)
M = 145g x 1kg/1000g
(cross out g, then multiply 145 to 1kg)
M = 145kg/1000 = 0.145kg
M = 0.145 kg
V = 30.00 m/s
Solution:
KE = 1/2mv^2
KE = 1/2(0.145kg)(30.00m/s)^2
(Square first the velocity)
KE = 1/2(0.145kg)(900.00m^2/s^2)
KE = 1/2(130.5 kg*m^2/s^2)
KE = 65.25 kg*m^2/s^2
(Reminder: 1 kg*m^2/s^2 = 1 J)
KE = 65.25 J
Final Answer:
65.25 J is the kinetic energy that the ball has.

I remember when I met you
the smile on your face,
Seems like a million years ago -
a different time and place
I remember when I kissed you
the warmth inside my heart,
I thought it'd last a lifetime
I swore we'd never part
I thought about the future
I started making plans,
Forever you'd be my woman
forever I'd be your man
We went together places
so that everyone could see,
The women that I want to share
the rest of my life with me
I told you that I loved you
I told you that I cared,
I told you if you were falling
just look back and I'd be there
I know I didn't have all the answers
sometimes I only guessed,
But, through it all I have to say
"I always tried my best"
I wasn't always perfect
I wasn't always right,
I know sometimes I wasn't
even worthy in your sight
I know I took for granted
the love you had to share,
All I ever wanted was
for you to know I cared
Our lives have changed directions
as sometimes lovers do,
Often time and change
and pave a path that's new
Sometimes I often wondered
just what lies ahead,
Sometimes I'd like to turn back time
and take back what I said
We've both gone different places
we've both gone different ways,
I know sometimes I let you down
when trouble came our way
I know sometimes I did things
you didn't comprehend,
But, through the years and all the tears
our memories will never end........
