<h2>Answer:</h2>

The displacement of <u>3190 m</u> a car can travel if velocity is accelerated uniformly for 50 m⁄s to 60 m⁄s over a 58 second interval.

<h2>Explanation:</h2>

A car traveling at 50 m⁄s to 60 m⁄s over a 58 second interval the displacement of car is found by using the formula:

s=\frac{1}{2}(v+u) t

Where,  

v is final velocity = 60 m/s

u is initial velocity = 50 m/s

t is time taken = 58 s

s is displacement

Now,

\Rightarrow s=\frac{1}{2}(60+50) 58

\Rightarrow s=\frac{1}{2}(110) 58

\therefore s=3190 \ m

Hence, a car travels 3190 m if velocity is accelerated uniformly for 50 m⁄s to 60 m⁄s over a 58 second interval.

Explanation:

here u = 50m/s

v = 60m/s

t = 58 s

then a = (60-50)/58 m/s2

= 0.17m/s2

now s= ut+1/2at2

so , 50×58+0.5×0.17×(58)^2 m

= 3185.94 m

= 3.18 km

A battery supplies 0.71 A to three resistors connected in parallel. The current through the first resistor is 0.27 A and the cur
Yuki888 [10]

Answer:

0.2 A

Explanation:

Current: This is the rate of flow of charge in a circuit. The S.I unit of charge is Ampere (A).

Note: When resistors are connected in parallel, the total current is equal to the sum of the individual current in each resistor.

It = I1 + I2 + I3......................... Equation 1

Where,

It = Total current, I1 = current in the first resistor, I2 = current in the second resistor, I3 = current in the third resistor.

Given: It = 0.71 A, I1 = 0.27 A, I2 = 0.24 A.

Substitute into equation 1

0.71 = 0.27+0.24+I3

0.71 = 0.51+I3

I3 = 0.2 A.

Hence the current through the third resistor = 0.2 A

Linear Velocity What is the linear velocity in cm&gt;min for any edge point of a 12-cm-diameter CD (compact disc) spinning at 10
daser333 [38]

3,89,988 cm/min is the linear velocity

Given,

Diameter of CD = 12 cm

So, Radius of CD = 6 cm

CD is spinning at 10350 rev/min

Firstly , convert rev/min into rad/min

1 rev = 2π radians

10350 rev/min = 10350 × 2π

                        = 64998 rad/min

Formula used,

v=rw where,

v is the Linear velocity

r is the radius

w is the angular velocity

v = 6 cm × 64998rad/min

  = 3,89,988 cm/min

Thus, linear velocity for any edge point of a 12-cm-diameter CD (compact disc) spinning at 10,350 rev/min is 389988 cm/min.

An egg is dropped from the top of the band hall. if the band hall is 25 m tall, determine the time it takes the egg to hit the f
Vera_Pavlovna [14]

Answer:

2.26 s

Explanation:

The following data were obtained from the question:

Height (h) = 25 m

Acceleration due to gravity (g) = 9.8 m/s²

Time (t) =..?

The time taken for the egg to hit the floor can be obtained as illustrated below:

h = ½gt²

25 = ½ × 9.8 × t²

25 = 4.9 × t²

Divide both side by 4.9

t² = 25 / 4.9

Take the square root of both side

t = √(25 / 4.9)

t = 2.26 s

Thus, it will take 2.26 s for the egg to hit the floor.
