Two objects charged with an equal amount of charge interact with each other with a force

Would a measured force of (46.5 0.8 N  ) be in agreement with a theoretically calculated force of (48.4 0.6 N  ) ? Show your w

Answer:

A measured force of (46.5 0.8 N  ) would not be in agreement with a theoretically calculated force of (48.4 0.6 N  )

Explanation:

From the question we are told that

Measured force is $F_M = [46.5 \pm 0.8 \ N ]$

Calculated force is $F_c = [48.4 \pm 0.6 \ N ]$

Generally the measured force in interval form is

$46.5 - 0.8 < F_M < 46.5 + 0.8$

=> $45.7 < F_M < 47.3$

Generally the calculated force in interval form is

$48.4 - 0.6 < F_c < 48.4 + 0.6$

=> $47.8 < F_M$

Generally looking both interval we see that they do not intersect at any point Hence

A measured force of (46.5 0.8 N  ) would not be in agreement with a theoretically calculated force of (48.4 0.6 N  )

Nadya [2.5K]

Emit greenhouse gases

Explanation:

Nuclear power is regarded as a clean energy source because it doesn't produce or emit greenhouse gases.

Greenhouse gases are mostly generated by the use of fossil fuels that pollutes the environment causing surging global temperature.

Nuclear power is produced by the splitting of radioactive minerals in rods. The process releases a large amount of energy. When the fuel elapses, only radioactive wastes remains.

There is no production of any greenhouse gas in the process of harnessing nuclear energy.

This is why it is considered a clean energy source.

A copper wire has a radius of 3.5 mm. When forces of a certain equal magnitude but opposite directions are applied to the ends o

denpristay [2]

Answer:

The tensile stress on the wire is 550 MPa.

Explanation:

Given;

Radius of copper wire, R = 3.5 mm

extension of the copper wire, e = 5.0×10⁻³ L

L is the original length of the copper wire,

Young's modulus for copper, Y = 11×10¹⁰Pa.

Young's modulus, Y is given as the ratio of tensile stress to tensile strain, measured in the same unit as Young's modulus.

$Y =\frac{Tensile \ stress}{Tensile \ strain} \\\\Tensile \ stress = Y*Tensile \ strain\\\\But, Tensile \ strain = \frac{extension}{original \ Length} = \frac{5.0*10^{-3} L}{L} = 5.0*10^{-3}\\\\Tensile \ stress = 11*10^{10} *5.0*10^{-3} \ = 550*10^6 \ Pa$

Therefore, the tensile stress on the wire is 550 MPa.

Aleksandr-060686 [28]

Answer:

Electrons revolves around the nucleus in a fixed orbits with fixed energy.

electron clouds.

Explanation:

Rutherford in his model of atom explained:

Maximum space inside the atom is empty.

Electron revolves around the the center called nucleus.

Nucleus contains the positive charge.

Bohr's in his model explained that:

Electrons revolves around the nucleus in a fixed orbit named as shells.

Each orbits or shells has fixed amount of energy and size.

A runner hopes to complete the 10,000-m run in less than 30.0 min. after running at constant speed for exactly 26.0 min , there

kykrilka [37]

Let v = the running speed
After running at constant speed for 26 min, the distance traveled is
d = (v m/min)*(26 min) = 26v m
Because there are 1500 m to go, the distance traveled is
10000 - 1500 = 8500 m

The running speed is
v = (8500 m)/(26 min) = 326.9 m/min
In km/h, the speed is
v = (0.3269 km/min)*(60 min/h) = 19.6 km/h

Answer: The running speed is 19.6 km/h
