Answer:
The mass of the object is 24.5 kg and weight of the object on Mars is 91.14 N.
Explanation:
Weight of the object on the surface of Earth, W = 245 N
On the surface of Earth, acceleration due to gravity, g = 10 m/s²
Weight of an object is given by :
W = mg
m is mass
[tex]m=\dfrac{W}{g}\\\\m=\dfrac{245\ N}{10\ m/s^2}\\\\=24.5\ kg[/tex]
So, the mass of the object is 24.5 kg
Acceleration due to gravity on Mars, g' = 3.72 m/s²
Weight of the object on Mars,
W' =mg'
W' = 24.5 kg × 3.72 m/s²
= 91.14 N
So, the weight of the object on Mars is 91.14 N.
Given the data in the question;
Weight of object; [tex]W = 245N[/tex]
What is the mass of the object.Weight the measure of the force of gravity pulling down on a particle or object.
It is expressed as:
[tex]W = m* g[/tex]
Where m is mass of the object and g is acceleration due to gravity { Acceleration due gravity of Earth [tex]g_{earth} = 9.8m/s^2[/tex] }
We substitute our values into the equation
[tex]245N = m * 9.8m/s^2\\\\245kg.m/s^2 = m * 9.8m/s^2\\\\m = \frac{245kg.m/s^2}{9.8m/s^2} \\\\m = 25kg[/tex]
Therefore, mass of the object located near the Earth surface is 25kg
Weight of the object on Mars where the gravity [tex]3.72m/s^2[/tex]
So on planet Mars; [tex]g = 3.72m/s^2[/tex], we know that mass of the object is [tex]25kg[/tex]
We substitute into our equation
[tex]W = m* g[/tex]
[tex]W = 25kg * 3.72m/s^2\\\\W = 93kg.m/s^2\\\\W = 93N[/tex]
Therefore, the weight of the object on Mars with the given gravity is 93 Newtons.

Which two options describles physical properties of matter?
A. a substance's pH
B. a substance's resistance to flow
C. a substance's ability to conduct electricity
D. whether a substance rusts
E. a substance's inability to combine with other substances
The correct options that describe the physical properties of matter are "A substance's resistance to flow," and "A substance's ability to conduct electricity." The correct options are B and C.
What is the physical properties of matter?Physical properties of matter are characteristics that can be observed or measured without changing the substance's identity. These properties can help us identify and classify different substances.
Here in the Question,
Let's consider each option one by one:
A. A substance's pH is a chemical property of matter, which indicates whether a substance is acidic, neutral, or basic. It depends on the substance's chemical composition and the concentration of hydrogen ions in it. Therefore, this option is not a physical property.
B. A substance's resistance to flow is a physical property, also known as viscosity. It refers to how easily a substance can flow or be poured. For example, honey has a high viscosity, while water has a low viscosity. This property depends on the intermolecular forces between the molecules of the substance, which affect how closely they pack together. Therefore, this option is a physical property.
C. A substance's ability to conduct electricity is a physical property that depends on its structure and the presence of charged particles, such as ions or electrons. Substances that can conduct electricity are called conductors, while those that cannot are called insulators. Metals are good conductors of electricity, while plastics are good insulators. Therefore, this option is also a physical property.
D. Whether a substance rusts is a chemical property that indicates how a substance reacts with other substances, specifically with oxygen. Rusting occurs when iron or steel reacts with oxygen in the presence of water, forming a reddish-brown compound called iron oxide. Therefore, this option is not a physical property.
E. A substance's inability to combine with other substances is also a chemical property that depends on the substance's reactivity. Inability to combine with other substances may be due to a substance's stable electronic configuration, such as noble gases. Therefore, this option is also not a physical property.
Therefore, options B and C are true.

what is the difference between beat and beat frequency.
Explanation:
The beat is a word used for sound waves. The beat frequency is the difference in frequency of two waves. ... In sound, we hear said beat frequency as the rate at which the loudness of the sound varies whereas we hear the ordinary frequency of the waves as the pitch of the sound.
Explanation:
Beats :--
A wave not only travels in space but it also propagates through time, so if the two waves can produce interference by overlapping in space they should also produce an interference pattern when they overlap in time, this phenomenon is called beats.
Beat Frequency :--
The beat frequency is when two sound waves with different frequencies come across each other, then their amplitude gets added and subtracted alternatively for a given time period. This leads to the growth of the sound to louder and softer.

A plane is traveling at a velocity of 90 m/s. It accelerates at a constant rate of 1.5 m/s2 until its velocity reaches 500 m/s. What distance did the plane cover while it was accelerating?
Answer:
The distance the plane covered while it was accelerating is 80,633.3 m
Explanation:
Given;
initial velocity of the plane, u = 90 m/s
acceleration of the plane, a = 1.5 m/s²
final velocity of the plane, v = 500 m/s
The distance covered by the plane is given as;
v² = u² + 2ad
where;
d is the distance covered by the plane;
500² = 90² + 2(1.5)d
500² - 90² = 3d
241900 = 3d
d = 241900 / 3
d = 80,633.3 m
Therefore, the distance the plane covered while it was accelerating is 80,633.3 m

Which statement best describes the overall function of the human respiratory system? A. The heart pumps blood containing carbon dioxide into the lungs, where it is absorbed. B. Oxygen is transferred into the blood, which circulates the gas throughout the body. C. Oxygen is taken into the lungs and exchanged for carbon dioxide, which is exhaled. D. Carbon dioxide is taken into the lungs and exchanged for oxygen, which is absorbed.
Answer:
C
Explanation:
During respiration, oxygen diffuses into the lung (carbon dioxide diffuses out), gets into the blood, and is transported around the body. The hemoglobin of the blood distributes the oxygen to the various cells and carbon dioxide from these cells diffuses into the blood. The blood travels back to the lung where the carbon dioxide is exchanged for oxygen once again. The carbon dioxide is eventually exhaled out of the nose.
The correct option is C.
the kinetic energy of an object of mass in moving with a velocity of 5 MS -1 is 25j what will be its kinetic energy when its velocity is doubled what will be its kinetic energy when its velocity is increased three times. please answer fast I will mark brainly
Answer:
When the speed is doubled, K = 100 J, when the speed is tripled, K = 225 J
Explanation:
Kinetic Energy
Is the type of energy an object has due to its speed. It's proportional to the square of the speed.
The equation for the kinetic energy is:
[tex]\displaystyle K=\frac{1}{2}mv^2[/tex]
Where:
m = mass of the object
v = speed at which the object moves
The kinetic energy is expressed in Joules (J)
The object has a kinetic energy of K=25 J when moving at v=5 m/s, thus the mass can be calculated by solving for m:
[tex]\displaystyle m=\frac{2K}{v^2}[/tex]
[tex]\displaystyle m=\frac{2*25}{5^2}=2[/tex]
m = 2 Kg
If the speed is doubled, v=10 m/s, the new kinetic energy is:
[tex]\displaystyle K=\frac{1}{2}2\cdot 10^2[/tex]
K = 100 J
If the speed is tripled, v=15 m/s, the new kinetic energy is:
[tex]\displaystyle K=\frac{1}{2}2\cdot 15^2[/tex]
K = 225 J
When the speed is doubled, K = 100 J, when the speed is tripled, K = 225 J
The accepted equations for force and elastic potential energy for a spring include a term called the spring constant, k (in N/m). How could you find the spring constant from a force vs displacement graph? Explain.
Explanation:
Accordibg to Hooke's law ,
F=-kx
the minus sign indicates that the force exerted by the spring is opposite to that of extension and the relation between force and extension is a linear one so in the graph it wll pass through the origin and x=0 F=0 and the k (spring constant) will be a constant

A girl delivering newspapers covers her route by traveling 3.00 blocks west, 4.00 blocks north, and then 6.00 blocks east. What is the total distance she travels?
Answer:
13 blocks
Explanation:
The total distance the student travels is 13 blocks.
Distance is the length of path covered during the motion of a body.
To find distance:
Total distance = Number of blocks to the west + number of blocks to the north + number of blocks to the east
Total distance = 3blocks + 4blocks + 6blocks = 13blocks
