Answer:

1124923453 electrons

Explanation:

The formula for charge in coulomb ,C =Current in amperes, A * Time in seconds, s

Given in question ;

Charge = 1.6 * 10⁻¹⁹ C

Current = 2.0 nA = 2*e⁻⁹ A

Calculate time in seconds as

1.6 * 10⁻¹⁹ = 2*e⁻⁹ * t

1.6 * 10⁻¹⁹ /2*e⁻⁹  = t

6.48e⁻¹⁶  s = t

So using t=6.48e⁻¹⁶  s and current =2*e⁻⁹ A , the charge will be;

C = 2*e⁻⁹  * 6.48e⁻¹⁶  =1.799e⁻¹⁰ C

But 1 coulomb = 6.25 x 10¹⁸ electrons

so 1.799e⁻¹⁰ C = ?,,,,{ 6.25 x 10¹⁸} *{1.799e⁻¹⁰} =  1124923453.06 electrons

Answer:

Balancing of forces,

In the X-direction:

-Tcos4.5^o +Tcos4.5^o=0

In the Y-direction:

Tsin4.5^o +Tsin4.5^o-m*g=0

2Tsin4.5^o=15*9.81

T=(15*9.81)/(2sin4.5^o)

=937.75 N

Therefore, tension in the rope is 937.75 N.

the acceleration due to gravity on earth is 9.80 m/s2. if the mass of a giraffe is 1,470 kg, what is the weight of the giraffe?
Brrunno [24]
Weight  = Mass * gravity

             =  1470* 9.8 = 14406 N  ≈ 14,400 N

A 200 g, 20 cm diameter plastic disk is spun on an axle through its center by an electric motor. What torque must the motor supp
Rama09 [41]

Answer: The torque required is 0.0471 N m.

Explanation:

Mass of the disc = 200 g = 0.2 kg (1 kg =1000 g)

Radius of the disc =\frac{Diameter}{2}= 10 cm = 0.1 m(1 m = 100 cm)

Angular acceleration = \alpha

\alpha =\frac{2\pi\times 1800}{60 \times 4 sec}=15\pi rad/s^2

Moment of inertia = \frac{1}{2}\times mass\times (radius)^2=\frac{1}{2}\times0.2 kg\times (0.1 m)^2=0.001 kg m^2

Torque=\alpha \times I=0.001 kg m^2\times 15\times 3.14 rad/s^2r=0.0471 N m

The torque required is 0.0471 N m.

In physics what do we use machines for
Tasya [4]

Answer:

hope it helps for you

Explanation:

A machine is an object or mechanical device that receives an input amount of work and transfers the energy to an output amount of work. For an ideal machine, the input work and output work are always the same. The six common simple machines are the lever, wheel and axle, pulley, inclined plane, wedge, and screw.
