Answer:

+0.625×10^19

Explanation:

A proton has a charge of 1.6×10-19 coulomb

Q=ne (equation showing quantization of charge )

n= Q/e

n=+1C/1.6×10^-19C = 0.625×10^19 protons

n=0.625×10^19 protons

3. An automobile accelerates 1.77 m/sover 6.00 s to reach the freeway speed at

Effectus [21]

The initial speed of the automobile is 49.84km/hr

<u>Explanation:</u>

Given:

Acceleration, a = 1.77 m/s²

Time, t = 6s

Final speed, v = 88 km/h

v = 88 X 0.278 m/s

v = 24.464 m/s

Initial speed, u = ?

We know,

v = u + at

On substituting the value in the formula we get:

24.464 = u + (1.77 X 6)

24.464 = u + 10.62

u = 24.464 - 10.62 m/s

u = 13.844 m/s

Converting u = 13.844 m/s to km/hr

1 m/s = 3.6 km/hr

13.844 m/s = 13.844 X 3.6 km/hr

u = 49.84 km/hr

Therefore, the initial speed of the automobile is 49.84km/hr

Crickets Chirpy and Milada jump from the top of a vertical cliff. Chirpy drops downward and reaches the ground in 2.70 s, while

Vinvika [58]

Answer:

Explanation:

Given

Time taken to reach ground is $t=2.7\ s$

Malda initial velocity $u=95\ cm/s$

Let h be the height of Cliff

using $h=ut+\frac{1}{2}at^2$

where, u=initial velocity

t=time

In first case chirpy drop downward thus u=0

$h=0+\frac{1}{2}(9.8)(2.7)^2$

$h=35.72\ m$

For Milada there is horizontal velocity u=95 cm/s=0.95 m/s[/tex]

time taken to reach the ground will be same so distance traveled in this time with 0.95 m/s horizontal velocity is given by

$R=u\times t$

$R=0.95\times 2.7=2.43\ m$

The AB rope is fixed to the ground at its A end, and forms 30º with the vertical. Its other end is connected to two ropes by mea

lana66690 [7]

Answer:

T = 80√3 N ≈ 139 N

W = 160 N

Explanation:

Sum of forces on B in the x direction:

∑F = ma

80 N sin 60° − T sin 30° = 0

T = 80 N sin 60° / sin 30°

T = 80√3 N

T ≈ 139 N

Sum of forces on B in the y direction:

∑F = ma

80 N cos 60° + T cos 30° − W = 0

W = 80 N cos 60° + T cos 30°

W = 40 N + 120 N

W = 160 N

Fig. 28-9 shows the cross-section of a hollow cylinder of inner radius a = 5 cm and outer radius b = 7 cm. A uniform current den

Dmitrij [34]

Answer:

1.507×10⁻⁴ T

Explanation:

a = 5 cm = 0.05 m

b = 7 cm = 0.07 m

j = 1 A/cm²

Distance from magnetic field = d = 10 cm = 0.1 m

μ₀ = Vacuum permeability = 4π×10⁻⁷ H/m

Magnetic of hollow cylinder

$\oint B.ds=\mu_0 I\\\Rightarrow B2\pi d=\mu_0 I\\\Rightarrow B2\pi d=\mu_0J\pi(b^2-a^2)\\\Rightarrow B=\frac{\mu_0J\pi(b^2-a^2)}{2\pi d}\\\Rightarrow B=\frac{4\pi\times 10^{-7}\times 1\times 10^{-4}\pi(0.07^2-0.05^2)}{2\pi 0.1}\\\Rightarrow B=1.507\times 10^{-4}\ T$

∴ Magnitude of the magnetic field at a distance d = 10 cm from the axis of the cylinder is 1.507×10⁻⁴ T
