What is the period of a wave that has a frequency of 30 Hz?
A. 0.3s
B. 0.03 s
C. 30 s
D. 35
Answer:
0.03s
Explanation:
Period of wave and its frequency are closely related. Period is the inverse of frequency.
The period of a wave is the time taken for a number of waves to pass through a particular point.
The frequency of a wave is the number of waves that passes through a point at a particular time.
So;
f = [tex]\frac{1}{T}[/tex]
f is the frequency
T is the period
Period of the wave = [tex]\frac{1}{30}[/tex] = 0.03s

b.A certain piece of copper wire is determined to have a mass of 2.00 g per meter.
How many centimeters of the wire would be needed to provide 0.28 g of
copper?
Help please!!
Answer:
14cm
Explanation:
Mass per gram of the piece of wire;
2g of the wire is found in 1m
Since
100cm = 1m;
So;
100cm of the wire contains 2g of the wire
To provide 0.28g
Since;
2g of wire is made up of 100cm
0.28g of wire will be contained in [tex]\frac{100 x 0.28}{2}[/tex] = 14cm
14cm of the wire will contain 0.28g

what is the KE if a 10kg mass traveling at 5 m/s
Answer: KE = 25 J
Explanation: You must use the formula
KE = 1/2 m v²
to solve this problem.
KE = 1/2 (10 Kg) (5 m/s)
KE = 1/2 (50 kgm/s)
KE = 25 J
The melting point of a substance is an example of?
Answer:
Melting point of a substance is the temperature at which a substance changes from a solid to a liquid. A change of state like melting is a physical change because it doesn’t alter the identity of the substance. In other words, melting point is a physical property because you can determine an object’s melting point without changing the substance. For example, when a substance like ice melts into water, the identity of the substance doesn’t change; the substance is water before and after the physical change. On the other hand, flammability is a chemical property because burning an object is a combustion reaction that leads to the creation of new substances. When you burn a piece of wood, it reacts with oxygen in the air to produce heat, light, carbon dioxide, and water vapor.

Answer:
B: Human body, organs, molecules, atoms neutrons. please correct me if im wrong
Explanation:
A P ex
The list that places different units of matter in the correct sequence from largest to smallest is as follows:
The human body, organs, molecules, atoms neutrons.What is the matter?Matter may be defined as a type of substance that possesses a specific mass and occupies space by having a specific volume. So, it certainly has both mass and volume. In nature, each and every object is made up of matter.
With respect to the question, the human body is the largest unit that consists of matter. The body of a human generally consists of numerous organ systems which are built through the collection of other different organs.
The organ is further made up of the collection of tissues that are formed by the collection of cells. Cells possess numerous molecules which are made of atoms. Atoms have three types of subatomic particles, i.e. electrons, protons, and neutrons.
Therefore, the list that places different units of matter in the correct sequence from largest to smallest is well mentioned above.

The area of contact of each of the four tyres with the ground is 0.025m2. Determine the minimum car tyre pressure
Answer:
The minimum pressure car tire pressure is 300,000 Pa
Explanation:
Pressure
It's a measure of the force exerted by an object per unit surface:
[tex]\displaystyle P=\frac{F}{A}[/tex]
Where F is the force applied on a surface area A.
We are given the total weight of a car with passengers as Ft=30,000 N and we also know the area of contact of each tire with the ground as [tex]A=0.025 m^2[/tex].
The minimum pressure each tire can have is when the total weight is evenly distributed in all four tires, thus F=Ft/4=7,500 N.
Calculating the pressure:
[tex]\displaystyle P=\frac{7,500}{0.025}[/tex]
P=300,000 Pa
The minimum pressure car tire pressure is 300,000 Pa

slope or velocit ime graph represent
2. What is instantaneous acceleration?
3. What is unit vector?
Answer:
Please check the explanation.
Explanation:
The slope of the velocity-time graph illustrates the change in velocity with respect to change in time.
In other words, the acceleration of the object is defined by the slope of a velocity graph. The acceleration can be obtained by finding the slope at a particular time.
Hence, the slope of the velocity time graph represent represents acceleration.
2. Also the acceleration of any object, like a car or bike, at some discrete instant in time 't' is termed as instantaneous acceleration which can be determined if we may take the derivate of the given velocity function.
3. A vector that has a direction and magnitude of 1 is termed as a unit vector, often called a direction vector.
A 0.15 kg project hits the ground with a speed of 11 m/s. The project comes to rest in 0.015 seconds. What is the net force?
Answer:
Explanation:
ACCORDING TO NEWTONS SECOND LAW;
F = mass * acceleration
F = m(v-u/t)
m is the mass = 0.15kg
v is the final velocity = 11m/s
u is the initial velocity = 0m/s
t is the time = 0.015
Substitute;
F = 0.15(11-0)/0.015
F = 0.15(11)/0.015
F = 1.65/0.015
F = 110N
Hence the net force is 110N

What is the mass number of an atom that has 5 protons and 7 neutrons? I give brainliest.
Answer:
The atomic mass of an atom that has 5 protons and 7 neutrons would be 12.
Explanation:
In all cases, the number of protons added to the number of neutrons equate to the mass of an atom. Electrons do have mass, but it's so miniscule and insignificant that it doesn't contribute to the overall mass of the atom, so there's no need to count them.
Bonus Information:
DO NOT CONFUSE MASS WITH CHARGE! Protons and neutrons are the only particles that contribute to the mass of an atom. Meanwhile, protons (+) and electrons (-) are the only particles that have a charge. As it says in its name, neutrons are neutral or have no charge.
Remember:
C = p - e
M = p + n
C = atomic charge, M = atomic mass, p =protons, n = neutrons, e = electrons

What is shown by the pattern of iron filings around these two magnets?
A. Opposite poles repel because no magnetic field forms between them.
B. Like poles attract because the magnetic field lines extend between them.
C. Like poles repel because the magnetic lined bend away from each other.
D. Opposite poles attract because the magnetic field lines cross each other.
The pattern of iron fillings around the magnet depicts that like poles repel because the magnetic lined bend away from each other. Thus, option C is correct.
What are magnetic field lines?The North Magnetic Pole would move via magnetic field lines, which are hypothetical lines. The magnet's oppositely polarized poles attract and repel one another.
Since the magnetic field lines inside the magnet run from the south pole to the north pole, Never do magnetic field lines cross one another. A closed loop is formed by magnetic field lines.
Because magnetic force lines are bending in the direction of the south pole in the illustration, like poles repel one another. If the magnetic lines are bent away from one another, like poles repel one another.
Thus, image given has the presence of lines bending away from each other, thereby are like poles repel. Hence, option C is correct.
