Answer:

Explanation:

The average speed of the boat:

[tex]\bar{v}=\frac{s}{t}=\frac{3.6}{80}=0.045[/tex] km/min

But if you want to change the unit into m/s, you only take this way:

[tex]0.045 \frac{km}{min}=\frac{0.045\times 1000}{60}=0.75[/tex] in m/s.

The average speed of the boat will be approximately 0.75 m/s.

Average speed is the rate of change of change of distance covered with time.

Given is a boat that sails for 80 minutes and travels 3.6 Km.

Distance covered by the boat [ΔD] = 3.6 Km = 3600 m

Time taken [Δt] = 80 minutes = 80 x 60 = 4800 s

Now, we can calculate the average speed using the formula -

s = ΔD/Δt

s = 3600/4800

s = 36/48

s = 0.75 m/s

Therefore, the average speed of the boat will be approximately 0.75 m/s.

The magnitude of the centripetal acceleration of the air plug on a car tire is 308.43 m/s².

Centripetal acceleration of an object is the rate of change of object's velocity with time, and it is directed inwards.

The magnitude of the centripetal acceleration of the air plug on a car tire is calculated as follows;

ac = ω²r

where;

[tex]\omega = 250 \ \frac{rev}{\min} \times \frac{2\pi \ rad}{1 \ rev} \times \frac{1 \min}{60 \ s} \\\\\omega = 26.18 \ rad/s[/tex]

ac = (26.18)² x 0.45

ac = 308.43 m/s²

Thus, the magnitude of the centripetal acceleration of the air plug on a car tire is 308.43 m/s².

Explanation:

The kinetic friction between crate and the surface can be calculated as follows: [tex]f_{k}=\mu_{k}N=\mu_{k}mg=(0.24)(2)(10)=4.8 N[/tex]

Assume that the direction of the 10 N constant force is on the right, the kinetic friction will go the left, then:

[tex]\sum F=F_{net}=F-f_{k}=10-4.8=5.2 N[/tex]

A constant force of 10 N is applied to a crate of mass 2 kg on a rough surface, then the net force on the crate is 5.2 N

Friction is the resistance to a thing sliding or rolling over another solid object. Although frictional forces can be helpful, such as the traction required to walk without sliding, they also provide a significant level of resistance to motion.

The forces of attraction, also called as adhesion, between both the contact zones of the surfaces, that are always microscopically uneven, seem to be the main contributor to friction among metals.

These "welded" joints are sheared, and friction is created by the irregularities of a harder surface scuffing down against the softer surface.

From the given data in the question,

Firstly, calculate the friction between the crate and the surface,

[tex]f_k\\[/tex] = [tex]\mu_k[/tex]mg

= (0.24)(2)(10)

= 4.8 N

Now, let's calculate the net force,

ΣF = F(N) = F - [tex]f_k[/tex]

= 10 - 7.8

= 5.2 N

Therefore, the net force will be equal to 5.2 N.

When waves are generated and they reflect off a fixed end, the reflected waves are completely out of phase. The reflected waves and the incident waves interfere with each other along the path and results in the formation of nodes and anti-nodes. Nodes are points of completely out of phase interference and anti-nodes are points of completely in phase interference.

The kinetic energy of the charged particle is equal to the work done to bring it from the distance of 1 m. Hence, the total electric force here is 0.025 N. Therefore, the charge on the fixed particle is  approximately + 6.7 µC.

According Coulomb's law the electrostatic force between two charges is given by ,

F =  k q1 q2 /r²

Where q1 and q2 be the charges and r be the distance between them, k be the constant equal to 8 × 10⁹ N m²/C².

Given q1 = + 5  µC

r = 1 m.

the kinetic energy in bringing the charge of  5 µC from 2 m is given 50 mJ.

then F = 0.05 J/2 m = 0.025 N

Then q2 = F r²/ (q1 K)

q2  = 0.025 N / ( + 5  µC × 8 × 10⁹ N m²/C²)

      =  6 µC.

Therefore, option b is the approximate charge of the fixed particle.
