Taipei, Taiwan has the world's fastest elevators. The peak speed can be 16 m/s while
the average speed is 15 m/s. How can the peak speed be higher than the average
speed?
Answer:
Because the average speed can be 0-16 m/s. But the peak speed must be 16 m/s.
Taiwan's Taipei has the world's fastest elevators. Since peak speed is the quickest that any moving body can go, it is greater than average speed. The average speed is 15 m/s, while the top speed may reach 16 m/s.
What is speed?Speed is the overall distance an item travels in a given amount of time.
speed =distance traveled /time consumed
Taiwan's Taipei has the world's fastest elevators. Because peak speed is the fastest that any moving body can move, it is why peak speed is greater than average speed.
The average speed is 15 m/s, while the top speed may reach 16 m/s.
While the average speed is an indication of the average.
Thus, the peak speed is higher than the average speed.

b. time-dependent magnetic field.
c. conductor moving in a magnetic field.
d. object moving in a magnetic field.
e. magnetic field.
Answer:
b. time-dependent magnetic field.
An electric field is associated with every time-dependent magnetic field.
What is electric field?An electric field is a physical field that surrounds electrically charged particles and acts as an attractor or repellent to all other charged particles in the vicinity. Additionally, it refers to a system of charged particles' physical field. The magnetic impact on moving electric charges, electric currents, and magnetic materials is described by a magnetic field, which is a vector field.
An electric field is produced by a time-varying magnetic field. The first law of Faraday states that an electromotive force is always produced when a conductor is exposed to a changing magnetic field. Induced current is the term for the current that results when the conductor circuit is closed.

How do Newton’s laws of motion explain why it is important to keep the ice smooth on a hockey rink so that players can pass a puck as quickly as possible?
Answer:
Newton's first law
Explanation:
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. Therefore, when the ice is smooth, friction gets lesser, and the force acted on that Puck will be decreased.
Answer:
The first law states that “objects at rest and objects in motion remain in motion in a straight line unless acted upon by an unbalanced force”. Keeping the ice smooth will make sure there is not friction, friction would slow the puck down

The first law states that “objects at rest and objects in motion remain in motion in a straight line unless acted upon by an unbalanced force”. Keeping the ice smooth will make sure there is not friction, friction would slow the puck down

What is Newton's second law of motion ?
Newton's second law of motion states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.
Initial mass = 950 kg
mass of piolet = 65 kg
reduced mass = 950 - 65 = 885 kg
according to Newton's second law of motion
force = mass * acceleration
3000 N = 885 kg * acceleration
acceleration = 3000 / 885 = 3.39 m/s^2 = 3.4 m/s^2

A racecar races on a circular race track. Calculate the average racing speed given that
distance around the track is 2500 m and the racecar does it in 40 seconds.
Answer:
Below
Explanation:
You can use this formula to find the average speed or velocity of an object
speed = displacement / elapsed time
Plugging in our values....
speed = 2500 m / 40 seconds
= 62.5 m/s
*if your teacher required you to round to significant figures, you would round this number to 60, as 40 seconds only has 1 significant figure (the number with the least amount of sig figs determines the number of sig figs in the final answer)*

The speed limit on Highway 85 is 65 mi/h. What is it in m/s?
Answer:
29 m/s
Explanation:
65 mi/hr (1 hr/3600s)(5280 ft/mi)(12 in/ft)(2.54 cm/in)(1 m/100cm) = 29.0576
The speed limit on Highway 85 in meters per seconds is 29.07m/s
Given the speed limit on highway 85 as 65mi/hr
Using the conversion rate:
2.23694 mi/hr = 1m/s
We are to convert 65mi/hr to m/s, we can therefore write:
65mi/hr = x
Divide both expressions
[tex]\frac{2.23594}{65} = \frac{1}{x} \\Cross \ mutiply\\ 2.23594x = 65\\x = \frac{65}{2.23594}\\x = 29.070m/s[/tex]
This shows that the speed limit on Highway 85 in meters per second is 29.07m/s

How net current on a toroid is zero?
Answer:
The concept of zero net current in toroid occurs when we try to determine magnetic field induction outside toroid.
to determine magnetic field outside toroid, we consider a circular loop outside toroid as shown in figure.
to get the net enclosed current inside the loop, let us consider the crosssection AA' in toroid as shown in figure
as we see the crosssection AA' part of figure, we see that currents in the winding are in opposition directions at near to the loop
and far away from loop. Hence the concept of net current zero occurs in toroid when we try to determine
magnetic field induction outside toroid.

A rocket, initially at rest, steadily gains speed for 4.00s while traveling upwards
70.0m.
What was the rocket's final speed?
Answer:
[tex]35.0\; \rm m \cdot s^{-1}[/tex].
Explanation:
The question states that the rocket gains speed steadily. In other words, the acceleration of this rocket in that four seconds would be constant.
Let [tex]a[/tex] denote the acceleration of this rocket.Let [tex]t[/tex] denote the duration of the acceleration.Let [tex]v_{0}[/tex] denote the initial velocity of this rocket.Let [tex]x[/tex] denote the displacement of this rocket.Using information from the question:
[tex]t = 4.00\; \rm s[/tex], [tex]x = 70.0\; \rm m[/tex],[tex]v_{0} = 0\; \rm m \cdot s^{-1}[/tex] since the rocket was "initially at rest".Apply the SUVAT equation [tex]\displaystyle \frac{1}{2}\, a \cdot t^{2} + v_{0}\cdot t = x[/tex] to find [tex]a[/tex], the acceleration of this rocket.
[tex]\displaystyle \frac{1}{2}\, a \times (4.00\; {\rm s})^{2} + 0 = 70.0\; \rm m[/tex].
[tex]\begin{aligned}a &= \frac{70.0\; \rm m}{\displaystyle \frac{1}{2} \times (4.00\; {\rm s})^{2}} = 8.75\; \rm m \cdot s^{-2}\end{aligned}[/tex].
In other words, this rocket accelerated from rest at a constant [tex]a = 8.75\; \rm m \cdot s^{-2}[/tex] for [tex]t = 4.00\; \rm s[/tex]. The final velocity of this rocket would be:
[tex]\begin{aligned}& v_{0} + a\cdot t \\ =\; & 0 \; \rm m\cdot s^{-1} + 8.75\; \rm m\cdot s^{-2} \times 4.00\; \rm s \\ =\; & 35.0\; \rm m\cdot s^{-1}\end{aligned}[/tex].
When an object of mass 200g is submerged in methanol, its apparent weight is 1.052N. When submerged in benzene its apparent weight is 0.951N. If the density of methanol is 0.8g/cm^3, What is the density of benzene?
When the object is submerged in methanol, it displaces an amount of methanol with weight 1.052 N, i.e. with mass = (1.052 N)/g ≈ 107.347 g. With a density of 0.8 g/cm³, this means the displaced methanol and hence the object itself have a volume of
v ≈ (107.347 g) / (0.8 g/cm³) ≈ 134.184 cm³
Likewise, when submerged in benzene, the object displaces 0.951 N of benzene, whose mass is (0.951 N)/g ≈ 97.041 g with the same volume as the object. So the density d of benzene is
d ≈ (97.041 g) / (134.184 cm³) ≈ 0.723 g/cm³
What topic name in physics does this equation belong to? g = Fg/m
