3. The average human walks at a speed of 5 km per hour. If your PE teacher asks you to
walk for
40 minutes in
gym class, how far would you walk (km)?

Answers

Answer 1

The average human walks at a speed of 5 km per hour. If your PE teacher asks you to walk for 40 minutes in gym class, you would walk for 3 Km.

What is Average speed?

The average speed is the  displacement of a particle divided into a time in which the displacement occurs. Instead, instantaneous speed is the limit of the average speed as the time interval approaches zero.

Usually,

Speed = Distance/ Time

Assuming you also walk with the average human walking speed of 5 km/h. We know the above formula of speed and now making distance the subject, distance is a product of speed and time.

Here, time is 40 minutes and if expressed in hours can be converted as,

40/60 = 0.6 hours.

Distance = 5 × 0.6

             = 3 km

Thus,the average human walks at a speed of 5 km per hour. If your PE teacher asks you to walk for 40 minutes in gym class, you would walk for 3 Km.

Answer:

  382.2 N

Explanation:

You want the normal force on an object weighing 437 N situated on an inclined plane 29° from the horizontal.

Force vector

The vector 437 N straight down can be decomposed to vectors parallel to the plane and perpendicular to the plane. That decomposition looks like ...

  (perpendicular, parallel) = 437 N · (cos(29°), sin(29°)) ≈ (382.2, 211.9) N

The normal force on the object is about 382.2 N.

a constant force is applied to an object, causing the object to accelerate at 10 m/s2 . what will the acceleration be if the force is halved and the object's mass is doubled? express your answer using two significant figures.

Answers

The acceleration is if the force is halved and the item's mass is doubled is 2.5 m/s².

Force is a push or pulls upon an item due to the item's interaction with a few different item. strain is a energy that could change the motion of an item. A force can purpose an object with mass to exchange its velocity, i.e., to boost up. stress also may be defined intuitively as a push or a pull. A force has each significance and route, making it a vector amount.

In the first case,

Let the mass of the object is = m

acceleration = 10 m/s²

The constant force F = ma

                             F = 10m   ---------(1)

New case 2,

force F' = F/2

mass M' = 2m

a = F'/M'

  = F/2 × 2m

a = F/4m

F = 4ma ----------(2)

dividing equations 1 and 2

   ⇒  [tex]\frac{F = 4ma}{F = 10m}[/tex]

a = 10/4

a = 2.5 m/s²

The phrase 'force' has a unique which means. At this degree, it's far truely appropriate to describe a pressure as a push or a pull. A force isn't always something that an item consists of or 'has in it. A pressure is exerted on one object thru another.

Draw your model to show what happens during the time when a balloon is being rubbed on a girl’s hair.

Answers

The electrons are transferred from hair to balloon when a balloon is being rubbed on a girl’s hair and attains a negative charge.

What happens when a balloon is rubbed with hair?

Rubbing the balloon against the hair leads to the transfer of electrons from the hair to the balloon because electrons are negatively charged, the balloon attains a negative charge, while on the other hand, the hair with the loss of negative charges gets a net positive charge. Static electricity occurs due to an imbalance between negative charges and positive charges in a body. These charges can build up on the surface of a body until they find a path to be released or discharged. Static electricity is produced when positive and negative charges are not in a balanced situation. Protons and neutrons don't move around but electrons jump from one place to another place. When an object has more electrons than protons, it has a negative charge.

So we can conclude that when a balloon is being rubbed on a girl’s hair, the electrons are transferred from hair to balloon.

When moving an object over a distance, an external force must direct at least a portion of its force in the direction of the displacement. This is referred to as work done in physics. If the force acting along the path is constant, the amount of work can be calculated by multiplying the length of the path by the force's component. The work W is equal to the force f times the distance h to express this idea mathematically, or W = mgh. The work is W = mas if the force is applied at an angle to the displacement.

a car enters the freeway with a speed of 5.9 m/s and accelerates uniformly for 3.3 km in 2.9 min. how fast is the car moving after this time?

Answers

The car will move fast with the velocity of 32.03 m/s

What is acceleration?Acceleration: the rate at which the speed and direction of a moving object vary over time. A point or object going straight ahead is accelerated when it accelerates or decelerates. Even if the speed is constant, motion on a circle accelerates because the direction is always shifting. Both effects contribute to the acceleration for all other motions.Acceleration is a vector quantity, since it has both a magnitude and a direction. A vector quantity is also velocity. The velocity vector change during a time interval divided by the time interval is the definition of acceleration. The limit of the ratio of the change in velocity during a given time interval to the time interval as the time interval approaches zero determines the instantaneous acceleration (at a specific time and location) For instance, acceleration will be stated in meters per second per second if velocity is expressed in meters per second.

Calculation

Initial velocity(u) = 5.9 m/s

Distance traveled = 3.3 km = 3300 m

Time = 2.9 min = 2.9×60 = 174 seconds

Formula,

[tex]s=\frac{1}{2} (u+v)t[/tex]

[tex]3300=\frac{1}{2} (5.9+v)*174[/tex]

[tex]v= (\frac{6600}{174} -5.9)m/s[/tex]

v = 37.93–5.9 = 32.03 m/s

When we plot a graph, the graph would always have to axes; the vertical axis and the horizontal axis. In this case, the vertical axis is the position and the horizontal axis is the time. The slope of this graph speaks of the displacement of the object.

Looking at the first graph, we can see that it can be able to show the motion of an object that went up and fell down as the speed of the object would decrease during the upward motion as it is decelerated due to gravity and comes to a halt at the maximum height before it is accelerated as it moves downwards.

From the graphs, the ranking of the displacements for the second set of graphs as; B> D > A> C. This is because there is a positive slope in B and D while the slope in A is zero and that in C is negative.

Can a spectrophotometer be used to measure the absorption of a particular wavelength of light that is not visible to the human eye?.

Answers

Yes, a spectrophotometer can be used to measure the absorption of a particular wavelength of light that is not visible to a normal human eye.

Even though we can't directly perceive this light's absorption, it can be quantified. We may calculate concentration by using a spectrophotometer, which detects the absorption of light at particular wavelengths (whether visible or not) by a solution. The number of chemicals in a solution or the amount of light absorption may be measured using the common and affordable method of spectrophotometry.

Each substance in the solution either absorbs or transmits light over a certain wavelength when a light beam is directed through the sample. Combining them with colored derivatives that are visible and measurable. Another is that colorless substances typically absorb light from the part of the spectrum that is invisible to the unaided eye, as measured by a spectrophotometer.
