A diver who is 10.0 m underwater experiences a pressure of 202 kPa. If the diver's surface area is 1.50 m.sq, with how much tota
Deffense [45]

The pressure on the diver is given by:

p=\frac{F}{A}

where F is the force exerted by the water on the diver, while A is the area of the diver.

In this problem, we know the pressure: p=202 kPa=2.02 \cdot 10^5 Pa, and the area of the diver, A=1.50 m^2, therefore we can rearrange the initial equation to find the force on the diver:

F=pA=(2.02 \cdot 10^5 Pa)(1.50 m^2)=3.03 \cdot 10^5 N

A long wire carrying I=1.1A of constant current oriented North-to-South (and the current is running northwards) is placed horizo
Tema [17]

Answer:

The absolute value of the angular deviation is 39.3°.

Explanation:

Given that,

Current = 1.1 A

Distance = 0.9 cm

Magnetic field = 20μT

We need to calculate the magnetic field due to wire

Using formula of magnetic field

B=\dfrac{\mu_{0}I}{2\pi d}

Put the value into the formula

B=\dfrac{4\pi\times10^{-7}\times1.1}{2\pi\times0.9\times10^{-2}}

B=24.4\times10^{-6}\ T

B=24.4\ \mu T

We need to calculate the absolute value of the angular deviation

Using formula of direction

\theta=\tan^{-1}(\dfrac{B_{E}}{B_{w}})

\theta=\tan^{-1}(\dfrac{20 \mu}{24.4 \mu})

\theta=39.3^{\circ}

Hence, The absolute value of the angular deviation is 39.3°.

Which one of the following accurately describes the force of gravity? A. The gravity acceleration has no effect on a body moving
attashe74 [19]
Answer: C
The gravity acceleration is in the same direction as the force of gravity, and thus toward the center of the earth.

Explanation:
All celestial bodies in our solar system experience forces between each other. On earth, the localized gravitational force in the earth's atmosphere is directed toward the center of the earth. It's magnitude is
32.174 ft/s² in English units,
9.807 m/s² in SI units.

All objects that have mass are subject to the earth's gravitational acceleration. The product of mass and the earth's gravitational acceleration defines the weight of an object as its gravitational force.
