Physics
1 answer:
Aleonysh [2.5K]3 years ago
3 0

Answer:

a.

Explanation:

in a

1 mi = 1.61km

so,in 50 miles

50 mi = 50 \times 1.61

= 80.5 \: km

in b

1 \: mi = 1760 \: yd

so in 22.3 miles

22.3 = 22.3 \times 1760

= 39248 \: yd

What happens if a mid-ocean ridge occurs on land
Gnesinka [82]

Answer:

Despite being such prominent feature on our planet, much of the mid-ocean ridge system remains a mystery. While we have mapped about half of the global mid-ocean ridge in high resolution, less than one percent of the mid-ocean ridge has been explored in detail using submersibles or remotely operated vehicles. so therefore we do not have enough information about them to know what will happen

Explanation:

A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary. Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt. The speed of spreading affects the shape of a ridge  slower spreading rates result in steep, irregular topography while faster spreading rates produce much wider profiles and more gentle slopes.

Radioactive nuclei decay to become unstable. Is this true or false?
Damm [24]

The unstable nuclei undergo radioactive decay. The nucleus decay in form of emitting the radiations or changing into the different chemical element.

Thus, the nucleus decay takes place till the nuclei become stable.

Hence, given statement is false.

A cube, whose edges are aligned with the , and axes, has a side length . The field is immersed in an electric field aligned with
Ivenika [448]

Complete Question

Complete Question is attached below

Answer:

q=1.558*10^{-9}c

Explanation:

From the question we are told that:

Side length s=1.13m

Left field strength E_l=784.75N/m

Right field strength E_r=776.38 N/m

Front field strength E_f=725.5 N/m

Back field strength E_b=749.54 N/m

Top field strength E_t=944.95 N/m

Bottom field strength E_{bo}=1082.58 N/m

Generally, the equation for  Charge flux is mathematically given by

\phi=EAcos\theta

Where

Theta for Right,Left,Front and Back are at an angle 90

cos 90=0

Therefore

\phi =0 with respect to Right,Left,Front and Back

Generally, the equation for  Charge Flux is mathematically also given by

\phi=\frac{q}{e_o}

Where

Area =L*B\\\\A=1.13*1.13\\\\A=1.2769m^2

Therefore

Q_{net}=E_{bo}Acos\theta_{bo} +E_tAcos\theta_t

Q_{net}=1082.85*1.2769*cos0=944.95*1.2769cos (180)

Q_{net}=176N/C m^2

Giving

q=\phi*e_0

q=176N/C m^2*1.558*10^{-12}c

q=1.558*10^{-9}c
