answer : mass of Bananas ( m ) = [tex]\frac{A^2}{V^2} * K[/tex]
To calculate for weight of Bananas = m * g where g = 9.8
Explanation:
Given an amplitude ( A )= 29.8981
Spring constant = x ( unknown )
maximum speed of Bananas( v ) = wA ( unknown )
question : calculate the weight of the bananas
First step : calculate the period of oscillation
T = [tex]\frac{2\pi }{vA}[/tex] --- ( 1 )
next step : express T in terms of mass ( m ) of the bananas
= [tex]2\pi \sqrt{\frac{m}{k} } = \frac{2\pi }{vA}[/tex]
∴ m/k = A^2 / v^2
hence mass of Bananas ( m ) = [tex]\frac{A^2}{V^2} * K[/tex]
To calculate for weight = m * g
Each of these flasks contains the same number of gas molecules. In
which container is the pressure highest?
Flask 1
Flask 2
Flask 3
Flask 4
Flask 3
Flask 4
Flask 2
Flask 1
Page
Answer:
Flask 1
Explanation:
when volume goes down pressure goes up, and the first flask has the smallest volume therefore the greatest pressure
We have that from the ideal gas equation that the flask with the lowest volume will have the highest pressure therefore
Flask one has the lowest Pressure
Option D
From the question we are told
Each of these flasks contains the same number of gas molecules. In
which container is the pressure highest
Generally the equation for an Ideal gas given as is mathematically given as
The ideal gass equation
[tex]PV=nRT[/tex]
Where
P=pressure
V=Volume
n=No of mole
R=Gas Constant
T=temperature
Therefore We have that from the ideal gas equation that the flask with the lowest volume will have the highest pressure therefore
Flask one has the lowest Pressure

If two micro coulomb of charge is flowing in a circuit for 5 minutes. What is the amount of current in the circuit?
Answer:
6.67×10¯⁹ A
Explanation:
From the question given above, the following data were obtained:
Quantity of electricity (Q) = 2 μC
Time (t) = 5 mins
Current (I) =?
Next, we shall convert 2 μC to C. This can be obtained as follow:
1 μC = 1×10¯⁶ C
Therefore,
2 μC = 2 μC × 1×10¯⁶ C / 1 μC
2 μC = 2×10¯⁶ C
Next, we shall convert 5 mins to seconds. This can be obtained as follow:
1 min = 60 secs
Therefore,
5 min = 5 min × 60 sec / 1 min
5 mins = 300 s
Finally, we shall determine the current in the circuit. This can be obtained as follow:
Quantity of electricity (Q) = 2×10¯⁶ C
Time (t) = 300 s
Current (I) =?
Q = It
2×10¯⁶ = I × 300
Divide both side by 300
I = 2×10¯⁶ / 300
I = 6.67×10¯⁹ A
Thus, the current in the circuit is 6.67×10¯⁹ A

If all the forces acting on an object are balanced then the net force acting on it is zero. True or, false?
Answer:
true
Explanation:
if all forces are equal then there would be no stronger force to give any net force so it would be zero

Answer:
The average speed for the runner B for the first 25 seconds was;
30/25 = 1.2 m/s
Explanation:
The average speed of an object is given by the following formula
[tex]Average \ speed = \dfrac{Total \ distance \ covered}{Total \ time \ taken \ to \ cover \ the \ distance}[/tex]
From the graph, we have;
The coordinates of the runner B at the start = (0, 0)
The coordinates of the runner B after 25 seconds = (25, 30)
The total distance covered by the runner B after 25 seconds = The difference between the position at 25 seconds and the origin which is 30 meters
∴ The total distance covered by the runner B after 25 seconds = 30 meters
The time it takes the runner B to cover the distance = The 25 seconds
[tex]\therefore \ For \ the \ runner \ B, the \ average \ speed = \dfrac{30 \ meters}{25 \ seconds} = 1.2 \ m/s[/tex]
The average speed for the runner B for the first 25 seconds = 30 m/(25 s) = 1.2 m/s.

Many people who have contracted a disease called chicken pox were told by their doctors that they would never have this
disease again. Why?
Answer:
Once you've had chickenpox you can't again.
Explanation: the virus remains inactive in your nerve tissue. Although it's unlikely you will get chickenpox again, the virus may reactivate later in life and cause a related condition called shingles.
A spring of force constant 1500 Nm-l is acted
upon by a constant force of 75 N. Calculate
the potential energy stored in the spring.
Answer:
1.876 J
Explanation:
First, let’s calculate the compression of the spring from the Hooke’s law:
F=kx,
here, F=75 N is the force acted on the spring, k=1500 N⁄m is the force constant of the spring, x is the compression of the spring.
Then, we get:
x=F/k=(75 N)/(1500 N/m)=0.05 m.
Finally, we can find the potential energy stored in the spring:
PE=1/2 kx^2=1/2∙1500 N/m∙(0.05 m)^2=1.875 J.
correct my answer if it's wrong ^^

6. Sandy adds 3 sugar packets to her tea in order to make it sweeter. She stirs in the sugar and then takes a sip. She notices that not all the sugar was dissolved. What type of solution did she make?
A. Saturated B.Unsaturated C.Supersaturated D.Mildly saturated
Answer:
C.Supersaturated
Explanation:
There are three types of solution:
SATURATED SOLUTION:
It is the solution that contains maximum amount of solute dissolved in a solution in normal conditions.
UNSATURATED SOLUTION:
It is the solution that contains less than the maximum amount of solute dissolved in a solution in normal conditions. It has space for more solute to be dissolved in it.
SUPERSATURATED SOLUTION:
It contains more than the maximum amount of solute dissolved in it. Such a solution has no capacity to dissolve any more solute under any conditions.
Since the sugar is no more dissolving in the tea and has settled down. Therefore, the solution is:
C.Supersaturated

Why are some forces considered to be noncontact forces? A. Objects must be far apart in order to exert a force. B. Objects do not have to touch each other to experience a force. C. Objects push each other apart to increase the distance between them. D. Objects must be large in size in order to exert a force that is strong enough to notice. is it a,b,c or d?
Answer:
B. Objects do not have to touch each other to experience a force.
Explanation:
For example ..One of the noncontact forces is magnetic force whereby a magnetic object will be attracted to another magnetic object of oppsite charged particles, through waves called electromagnetic waves. On the other hand, the two magnetic objects of similar charged particles can repel through electromagnetic waves..
Magnetic objects will attract to a magnet even if they are far from it.
Yes or No
Answer:
Yes
Explanation:
tamad ako magexplain
Answer:
Yes
Explanation:
The force exerted by a magnet is called
The push or pull of magnetism
can act at a distance, which means that the
magnet does not have to touch an object
to exert a force on it. When you close the
refrigerator, you feel the pull before the
magnet actually touches the metal frame.
There are other forces that act at a distance,
including gravity and static electricity. Later
you will read how the force of magnetism is
related to electricity. In fact, magnetism is
the result of a moving electric charge.

Why must the Moon travel more than a full orbit around the Earth for the full moon to be complete?
Answer:
The difference between the sidereal and synodic months occurs becuase as our moon moves around the earth, the earth also moves around our sun. Our moon must travel a little farther in its path to make up for the added distance and complete the phase cycle.

have a nice day
Answer:
Hey mate.....
Explanation:
This is ur answer.....
Wind is the movement of air caused by the uneven heating of the Earth by the sun. ... Warm equatorial air rises higher into the atmosphere and migrates toward the poles. This is a low-pressure system. At the same time, cooler, denser air moves over Earth's surface toward the Equator to replace the heated air.

Sometimes hikers carry radio beacons so that search and rescue teams can find them in case of emergency. Some of these beacons transmit radio waves with a frequency of 300,000 Hz. (300kHz) What is the wavelength of these waves?
Answer:
1000 m
Explanation:
Given that,
The frequency of radio waves f = 300,000 Hz
We need to find the wavelength of these waves.
The formula to find wavelength is as follows :
[tex]c=f\lambda\\\\\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{300000}\\\\\lambda=1000\ m[/tex]
So, the wavelength of these waves is 1000 m.
