I am using the equation F=ma (force equals mass times acceleration) to solve these problems.
1. You are looking for force, and have mass and acceleration. You just plug in the values for mass and acceleration to get the force needed.
F=(15kg)(5m/s^2)
F=75N
2. Again, you are looking for force, and just need to plug in the values for mass and acceleration
F=(3kg)(2.4m/s^2)
F=7.2N
3. In this problem, you have force and mass, but need to find acceleration. To do this, you need to get acceleration alone on one side of the equation - divide each side by m. Your equation will now be F/m=a
a=(5N)/(3.7kg)
a=18.5m/s^2
I did not use significant figures. Let me know if you need to do that and need any help on that. Hope this helps!
What increase in temperature is needed to increase the length of an aluminum meterstick by 1.0 mm?
42 K
24K
Answer:
42k
Explanation:
The increase in temperature is needed to increase the length of an aluminum meter-stick by 1.0 mm is 42 K. The option 1 is the correct option.
What is thermal expansion?Thermal expansion is the property of the matter to change its shape, size, length, volume, density etc with change in the temperature.
The thermal expansion can be calculate as,
[tex]\Delta L=aL\Delta T[/tex]
Here, [tex]L[/tex] is the original length, [tex]\Delta T[/tex] is the change in the temperature and [tex]a[/tex] is the coefficient of the expansion.
Given information-
The change in the length of the aluminum mater-stick is 1.00 mm.
Let the initial size of the aluminium mater-stick is 1.00 m or 1000 mm . The thermal expansion coefficient of aluminium is [tex](2.4\times10^{-5})[/tex] per unit Kelvin.
Put the values in the above formula as,
[tex]1=(2.4\times10^{-5})\times 1000\times\Delta T[/tex]
Solve for temperature as,
[tex]\Delta T=\dfrac{1}{(2.4\times10^{-5})\times 1000} \\\Delta T=42K[/tex]
Hence the increase in temperature is needed to increase the length of an aluminum meter-stick by 1.0 mm is 42 K. The option 1 is the correct option.

the body of mass 17 kg is attached to a string of length of 3.4 m is whirled round in vertical circle .if the tension in the string at the lowest point is 300N .calculate the speed of the body
Answer:
Speed of the body = 5.1652 m/s
Explanation:
Given:
Mass M = 17 kg
Length of string = 3.4 m
Tension in the string = 300N
Find:
Speed of the body
Computation:
T - mg = mv² / R... [R = L]
So,
T - mg = mv² / L
300 - 17[9.8] = [17][v]² / [3.4]
133.4 = [17][v]² / [3.4]
v² = 26.68
Speed of the body = 5.1652 m/s
Please help me I don’t get how to do it!!! A ray of light has a wavelength
433 nm in water (n = 1.33). What
is its wavelength in a vacuum?
(Remember, the wavelength is longer in
a vacuum.)
(Unit = nm)
Answer:
The wavelength of the light in a vacuum is 575.89 nm
Explanation:
The given parameter in the are;
The wavelength of the ray of light in water, λ₁ = 433 nm
The refractive index of water, n₁ = 1.33
The relationship between wavelength, λ, and refractive index, 'n', is presented as follows;
λ₁·n₁ = λ₂·n₂
Where;
λ₁ and λ₂ are the wavelength of the wave within the two mediums
n₁ and n₂ are the respective refractive indices of the mediums
The refractive index of vacuum, n₂ = 1
Let λ₂ represent the wavelength of light in vacuum
Therefore, we have;
1.33 × 433 nm = 1 × λ₂
∴ λ₂ = 1.33 × 433 nm/1 = 575.89 nm
Therefore, the wavelength in a vacuum, λ₂ = 575.89 nm

Answer:
The volume is the same apply this formula Pv=nRT shows direct proportionality this is what shows so we can take only PV=T and v stays the same.

Determine the force of gravitational attraction between the earth (m = 5.98 x 10^24kg)
and a 70-kg physics student, where the student is at a distance of 6.39 x 10^6 m from earth's
center.
Answer:
F = 683.8 N
Explanation:
The gravitational force of attraction between the Earth and the student is given by Newton's Law of Gravitation as follows:
[tex]F = \frac{Gm_{1}m_{2}}{r^2}[/tex]
where,
F = Force = ?
G = Universal gravitational constant = 6.67 x 10⁻¹¹ Nm²/kg²
m₁ = mass of Earth = 5.98 x 10²⁴ kg
m₂ = mass of student = 70 kg
r = distance between Earth and student = 6.39 x 10⁶ m
Therefore,
[tex]F = \frac{(6.67\ x\ 10^{-11}\ Nm^2/kg^1)(5.98\ x\ 10^{24}\ kg)(70\ kg)}{(6.39\ x\ 10^6\ m)^2}\\[/tex]
F = 683.8 N
Can an object in motion ever change directions?
Answer:
Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity.

This force is a pull between all objects. It is the force that gives us weight here on Earth. And, if we throw a rock off of a cliff, it is the force that causes the rock to fall to Earth. What is this force?
Answer:
Gravity.
Explanation:
Gravity is considered to be a universal force of attraction which acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.
Additionally, the gravity of earth makes it possible for all physical objects to possess weight.
This ultimately implies that, this force is a pull between all objects. It is the force that gives us weight here on Earth. And, if we throw a rock off of a cliff, it is the force that causes the rock to fall to Earth.

Which of the following collections of properties contain only features which can be changed by a resultant force?
The collections of properties which contain only features that can be changed by a resultant force is: speed, shape and direction.
A resultant force refers to a total effective force that has both magnitude and direction, which is mainly obtained through the addition of two (2) or more forces.
Hence, a resultant force is a single force acting on an object or physical body and it is obtained by combining two (2) or more forces.
Generally, there are some properties that changes when a resultant force is applied on them and these include:

State Newton's three laws of motion.
Answer:
Newton's first law states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
Newton's second law states that the acceleration of an object is directly related to the net force and inversely related to its mass. Acceleration of an object depends on two things, force and mass.
Newton's third law states that if an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A. This law represents a certain symmetry in nature: forces always occur in pairs, and one body cannot exert a force on another without experiencing a force itself.

tin shear have longer handles than than the scissor used to cut cloth give reason
Answer:
For scissor, small movement at effort(at handle) should make long movement of load arm , so that it can cut longer lengths of cloth/paper. Hence blades are longer than handle.so its handle(load arm) is made longer than its blades.

A car is traveling at 75 m/s. 50 seconds later it is traveling at 25 m/s. What is the car’s acceleration?
Answer:
a = -1 m/s^2
Explanation:
Vi = 75 m/s
Vf = 25 m/s
t = 50 s
Plug those values into the following equation:
Vf = Vi + at
25 = 75 + 50a
---> a = -1 m/s^2
