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

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.

Using information from the question:

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].

We have that the total pipe drip of [tex]X=155 mL/min.[/tex] expressed in gallons/day is

[tex]X=58.96gal/day[/tex]

From the Question we are told that

Pipe Drip[tex]=155 mL/min.[/tex]

Generally

We have that for mL to gallons conversion

[tex]1mL=0.000264172[/tex]

And

A minute to day con version is

[tex]1min=0.000694444[/tex]

Therefore

[tex]X=155 mL/min.[/tex]

[tex]X=155(\frac{0.000264172}{0.000694444})[/tex]

[tex]X=58.96gal/day[/tex]

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

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.

The answer you are looking for is 22 mph.

Solution:

s=speed

d=distance

t=time

Setting up the formula for the speed of an object with distance and time:

s=d/t

Substituting the given values,

s=88 miles/4 hours

So, therefore, the final answer is 22 mph.

I hope this helped answer your question for you. Good day to you.

9.  Healthy

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)*

Answer:

b. time-dependent magnetic field.

An electric field is associated with every time-dependent magnetic 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.

An electric field is associated with every time-dependent magnetic field.

-The acceleration due to gravity goes with the two inflated balls

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

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.

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.
