If the briefcase hits the water 6.0 s later, what was the speed at which the helicopter was ascending?

vovikov84 [41]

Complete Question

In an action movie, the villain is rescued from the ocean by grabbing onto the ladder hanging from a helicopter. He is so intent on gripping the ladder that he lets go of his briefcase of counterfeit money when he is 130 m above the water. If the briefcase hits the water 6.0 s later, what was the speed at which the helicopter was ascending?

Answer:

The speed of the helicopter is $u = 7.73 \ m/s$

Explanation:

From the question we are told that

The height at which he let go of the brief case is h = 130 m

The time taken before the the brief case hits the water is t = 6 s

Generally the initial speed of the briefcase (Which also the speed of the helicopter )before the man let go of it is mathematically evaluated using kinematic equation as

$s = h+ u t + 0.5 gt^2$

Here s is the distance covered by the bag at sea level which is zero

$0 = 130+ u * (6) + 0.5 * (-9.8) * (6)^2$

=> $0 = 130+ u * (6) + 0.5 * (-9.8) * (6)^2$

=> $u = \frac{-130 + (0.5 * 9.8 * 6^2) }{6}$

=> $u = 7.73 \ m/s$

A wire, of length L = 4.1 mm, on a circuit board carries a current of I = 1.96 μA in the j direction. A nearby circuit element g

tamaranim1 [39]

Answer:

The magnitude of the magnetic field B is 5.921 T.

Explanation:

Given that,

Length = 4.1 mm

$B_{x}=4.9\ G$

$B_{y}=2.3\ G$

$B_{z}=2.4\ G$

Current $I = 1.96\ mu A$

We need to calculate the magnetic field

Using formula of magnetic field

$B=\sqrt{B_{x}^2+B_{y}^2+B_{z}^2}$

Put the value into the formula

$B=\sqrt{(4.9)^2+(2.3)^2+(2.4)^2}$

$B=5.921\ T$

Hence, The magnitude of the magnetic field B is 5.921 T.

The garcias like to keep their 40.0 watts front prch light on at night to welcome visitors. if the light is on from 6pm until 7a

Gnesinka [82]

Answer:

For 1 week total cost will be equal to 0.2912

Explanation:

We have given power P = 40 watt

Light is on from 6 pm to 7 am

So total time = 13 hours

We know that energy is given by

$Energy=power\times time$

So energy will be $E=40\times 13=520watt-hour=0.520Kwh$

We have given cost per KWh is 0.08

So total cost per day will be = 0.08 ×0.520 = 0.0416

For 1 week that is for 7 day total cost will be = 7×0.0416 = 0.2912

Read the excerpt from Neil deGrasse Tyson’s “Death by Black Hole.” Black holes are regions of space where the gravity is so high

kramer

<h2>Answer: a definition of the term black hole</h2>

This text is clearly a definition of the term black hole, made by the American astrophysicist Neil deGrasse Tyson.

However, the discussions about this subject are not new, since Einstein's theory of relativity already defined what a black hole is.

In this sense, a black hole is described as a "singularity" that consists of <u>a region of the space in which the density of matter tends to infinity.</u>

Although this is hard to find possible for classical physics; following what relativity establishes:<em> bodies within a gravitational field follow a curved space path. Then the more a body enters the black hole, the more curved the space will become, until, in the center, it will become infinitely curved. </em>
