At a depth of 10.9 km, the Challenger Deep in the Marianas Trench of the Pacific Ocean is the deepest site in any ocean. Yet, in

1960, Donald Walsh and Jacques Piccard reached the Challenger Deep in the bathyscaph Trieste. Assuming that seawater has a uniform density of 1024 kg/m3, approximate the hydrostatic pressure (in atmospheres) that the Trieste had to withstand. (Even a slight defect in the Trieste structure would have been disastrous.)

Answer:7434.47 atmosphere

Explanation:

hydrostatic pressure (in atmospheres) = atmospheric pressure + pressure at depth

specific gravity = density of substance / density of water = 1024/1000= 1.024

specific weight = 1.024 * 9.79 kN/m^3 = 10.02496 kN/m^3

= 14.7 psi + 10.02496 kN/m^3* 10.9 km * 1000m = 109286.764 psi (1km = 1000m)

to atmosphere = 109286.764 psi/14.7 psi * 1 atmosphere = 7434.47 atmosphere

Answer:

P = 1081.304\,atm

Explanation:

The hydrostic pressure is equal to:

P = P_{atm} + P_{man}

P = 1\,atm + \left(\frac{1\,atm}{101,325\,Pa} \right)\cdot \left(1,024\,\frac{kg}{m^{3}} \right)\cdot (9.807\,\frac{m}{s^{2}} )\cdot (10,900\,m)

P = 1081.304\,atm

a cell phone uses 3.0V battery. the circuit board needs a 0.05 A current. what size resistor is needed to generate this current
san4es73 [151]

Answer:

60 Ohms

Explanation:

Ohms law states that the voltage in the circuit is directly proportional to the current through the circuit components and expressed as

V=IR

Where V is the voltage, I is current and R is resistance

Making R the subject of the formula then

R=\frac {V}{I}

Substituting 3.0V for V and 0.05 A for I then

R=\frac {3}{0.05}=60.0

Therefore, resistance is 60.0 Ohms

Why is Einstein's description of gravity called a theory, while Newton's is a law?
Ludmilka [50]
Albert Einstein came up with the theory of general relativity to explain the law of gravity, whilst Newton's three laws of gravity is universal. To understand this further, it's best to understand it in scientific terms.

The weird thing about science is that words that are used in a colloquial sense may have a completely opposite definition in scientific terms.

A law in science is a constant and invariable statement that is universal. Wherever you may be in the universe, Newton's three laws of gravity will always be applied.

The word "theory" doesn't imply conjecture or an idea someone made up after a night of drinking. In science, a theory is the highest level of certainty behind mathematical proof -- which isn't even a part of science, obviously. A theory has to be substantiated by all available evidence and contradicted by none. All theories also have to have to be falsifiable. For this reason, theories can never be proven. Einstein's theory of general relativity has great predictive power, but in some cases, the predictions aren't always constant. Theories are often revised to fit new available evidence.
