Machine weights are safer when used correctly, but free weights can be dropped and cause injury. These are safety considerations to keep in mind whether using free weights or machine weights. But because they aren't big, complicated machinery, free weights are less expensive.
What are free weights or machine weights?Resistance machines and free weights are very different from one another in terms of how they work and the results they can create.
Machines are set in place and can only move in a few directions, whereas free weights can be moved in whatever direction the user selects. This is the main distinction between machines and free weights. Free weights require you to utilize more stabilizing muscles to control them, whereas resistance machines help you by stabilizing you while you move.

Somebody pls help me with this question!
Answer:
speed are different at different places
Explanation:
because it's top speed is 50km/h,so it's initial speed may be less. when it covers some distance it's speed changes again. then we have given a mean speed .mean speed means sum of all speed divided by sum of total time.so the mean speed and final speed differs from each other

1. A particular lever is 90.0% efficient. If 50.0 J of work are done on the lever, then how much work does the lever do on its load? 2.The mechanical advantage of a pulley system is 4.00. Using this pulley system, how much force do you need to exert to lift a 500.0 N box?
Answer:
Explanation:
Using the efficiency formula;
Efficiency = Work done by the machine (output)/work done on the machine (input) ×100%
Efficiency =w/50 ×100
90 = 100w/50
Cross multiply
90×50 = 100W
4500 = 100W
W = 4500/100
W = 45Joules
Hence the lever does 45Joules of work on its load
2) Mechanical Advantage= Load/Effort
Given
MA = 4
Load = 500N
4 = 500/Effort
Effort = 500/4
Effort =125N
Hence the effort required to lift the load is 125N
1. The work done by the lever on its load is 45 J
2. The force needed to exert to lift the load is 125 N.
1. Determination of the work done by the lever on the load.
Work Input = 50 J
Efficiency = 90%
Work Output =?[tex]efficiency \: = \frac{work \: output}{work \: input} \times 100 \\ \\ 90\% = \frac{work \: output}{50} \\ \\ cross \: multiply \\ \\ work \: output \: = 90\% \: \times 50 \\ \\ work \: output = 0.9 \: \times 50[/tex]
Work Output = 45 JTherefore, the work done by the lever on the load is 45 J
2. Determination of the force needed to lift the load
Mechanical advantage (MA) = 4
Load (L) = 500 N
Effort (E) = ?[tex]mechanical \: advantage \: = \frac{load}{effot} \\ \\ 4 \: = \frac{500}{effort} \\ \\ cross \: multiply \\ \\ 4 \: \times effort \: = 500 \\ \\ divide \: both \: side \: by \: 4 \\ \\ effort \: = \frac{500}{4} \\ [/tex]
Effort = 125 NTherefore, the force needed to lift the load is 125 N

A crate weighing 523 N rests on a plank that makes a 22.0 angle with the ground. Find the components of the crate's weight force parallel and perpendicular to the plank. ( Fgx = –196 N, Fgy = –485 N)
Answer:
Explanation:
The weight of the crate will e equal to its normal reaction R
Since R = mgsin theta = W
W = mgsintheta ( resolved along the vertical perpendicular to the plank
Fy = 523sin22°
Fy = 195.92N
Since the weight is acting along the negative y direction,
Fy = -195.92N
The force parallel to the plank will be the force acting in the horizontal direction.
Fx = Fcos theta
Fx = 523cos 22°
Fx = 484.9N

Explanation:
When a negative magnification is obtained, it means that the image is inverted. When an object is placed far away from a converging lens than the focal length, the image is formed on the opposite side of the lens. In this case, a screen is introduced at image position for viewing. The image is focused up-side down. It is real and inverted.
3. As the ice melts into liquid water, what happens to the kinetic energy of the particles in the sample?
4. How does the kinetic energy of the particles in the sample relate to the sample’s temperature?
Answer:
As ice melts into water, kinetic energy is being added to the particles. This causes them to be 'excited' and they break the bonds that hold them together as a solid, resulting in a change of state: solid -> liquid.
Explanation:
As the ice melts into liquid water, the kinetic energy of the particles in the sample increase. The temperature of the sample is directly proportional to the kinetic energy of the particle.
What is Kinetic energy?The kinetic energy of an object is the energy which it possesses due to the motion of the object. Kinetic energy is defined as the work which is needed to accelerate a body of a given mass from the rest position to its stated velocity. The body of an object maintains the same amount of kinetic energy which it gained during its acceleration unless its speed changes.
The temperature is directly proportional to the kinetic energy of the object. As the temperature of the object increases the phase of the object changes from solid to liquid.

When a solid object absorbs infrared rays, what happens to the particles
in that object?
Answer:
All objects emit and absorb infrared radiation. The hotter an object is the more energy it radiates per second. Infrared radiation can travel through a vacuum. When infrared radiation hits an object some of the energy is absorbed, making the objects temperature increase, and some is reflected.

Which shows the correct angle of reflection given the incident ray shown?
[tex]\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Rays of light.
Since we know that, The light ray on a shiny surface makes a angle with the normal, hence The Angle of incidence is equal to angle of reflection made with Normal Axis in the middle.
Thus Option c.) is correct.
C.) is the Answer.
The angle of reflection given the incident ray from the given diagrams is option C.
What is the refraction of light?When a light ray strikes the shining surfaces, the part of the light gets refracted. The bouncing back of the light is called reflection. When the light strikes the surface is called an incident ray.
When the light ray incident on the surface, the light returns back to the same medium is called reflection. The laws of reflection are, the angle of incidence is equal to the angle of reflection, and the incident ray, reflected ray, and normal takes place in the same plane. The speed of light remains the same in the process of reflection.
The reflected light ray changes the path of direction in the same medium. When a light ray enters from one medium to another, the speed of light gets decreases.
Thus, the ideal solution is option C.

What is latent heat ?The quantity of heat (in joules or calories) per mole or unit mass of the substance undergoing a change in state is the typical way to represent latent heat.
The latent heat involved in melting solids or freezing liquids is referred to as the "heat of fusion," while the latent heat involved in vaporizing solids or liquids or condensing vapor is referred to as the "heat of vaporization."
When water boils at 100°C and turns into steam, water vaporizes into steam by absorbing heat of vaporization. This heat energy remains in the steam as kinetic energy and makes their movement fast.
So, The molecules will have more space between them and will be moving at higher speeds as steam compare to water.
