The package will fall 45.14 meters before hitting the ground, and it will take 3.06 seconds to do so. The horizontal velocity of the helicopter does not affect the time it takes for the package to fall, only the horizontal distance it travels.

When the package is released from the helicopter, it will experience two types of motion: horizontal and vertical. The horizontal motion will be at a constant velocity of 40m/s, while the vertical motion will be due to the force of gravity pulling the package downwards.

Since the effects of air resistance can be ignored, we can assume that the only force acting on the package is gravity. Using the formula for vertical motion under constant acceleration, we can find the time it takes for the package to reach the ground.

d = 0.5 * g * t^2, where d is the distance traveled, g is the acceleration due to gravity (9.81 m/s^2), and t is the time taken.

Rearranging this formula gives: t = sqrt(2d/g).

Substituting d = 0.5 * g * t^2 = 0.5 * 9.81 * (3.06)^2 = 45.14m, we get t = sqrt(2*45.14/9.81) = 3.06s, which is the time it takes for the package to reach the ground.

Answer:

Huh?

Explanation:

To calculate the resistance in the circuit, you can use Ohm's Law, which is V = I * R, where V represents voltage, I represents current, and R represents resistance.

Given that the circuit has 48 amps of current (I) and an applied voltage of 240 volts (V), you can rearrange Ohm's Law to find the resistance:

R = V / I
R = 240 volts / 48 amps

R = 5 ohms

So, the correct answer is:
a. 5 ohms

Answer:

2.38 m/s

Explanation:

Momentum is conserved:

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

After the collision, they move at the same speed, so v₁ = v₂ = v.

m₁u₁ + m₂u₂ = (m₁ + m₂) v

Plugging in numbers:

(115 kg) u₁ + (133 kg) (-1.59 m/s) = (115 kg + 133 kg) (0.250 m/s)

u₁ = 2.38 m/s

Answer:

0.0124 AU

Explanation:

Ganymede takes 7.15 Earth days to orbit Jupiter. Ganymede is measured to be 7.1 X 10⁻³ AU from Jupiter’s center.

We need to find how far away is Callisto from the center of Jupiter if a second moon of Jupiter, Callisto, takes 16.69 Earth days to orbit Jupiter. Let it is r₂. Using third law of Kepler.

\(T^2\propto r^3\)

i.e.

\((\dfrac{T_1}{T_2})^2=(\dfrac{r_1}{r_2})^3\\\\\dfrac{r_1}{r_2}=(\dfrac{T_1}{T_2})^{2/3}\\\\r_2=\dfrac{r_1}{(\dfrac{T_1}{T_2})^{2/3}}\\\\r_2=\dfrac{7.1\times 10^{-3}}{(\dfrac{7.15}{16.69})^{2/3}}\\\\r_2=0.0124\ \text{AU}\)

So, Callisto is 0.0124 AU from the center of the Jupiter.

the correct answer is 10 wires

Explanation:

Answer:

a)   y = y₀ - 4.9, v = -9.8 m / s, b)  y =y₀ - 19.6,  v = - 19 m / s

c)  y =y₀ - 44.1, v = - 29.4 m / s

Explanation:

To solve this exercise let us use the kinematic relations

          y =y₀ + v₀ t - ½ g t²

          v = v₀ - g t

They indicate that the body is released therefore the initial velocity is zero v₀ = 0

          y = y₀ - ½ g t²

          v = - gt

a) the position and velocity for t = 1s

         y = y₀ - ½ 9.8 12

         y = y₀ - 4.9

         v = - 9.8 1

         v = -9.8 m / s

the negative sign indicates that the velocity is directed downwards

b) t = 2 s

         y =y₀ - ½ 9.8 2 2

         y =y₀ - 19.6

         v = - 9.8 2

         v = - 19 m / s

c) t = 3 s

        y = y₀ - ½ 9.8 3 2

        y =y₀ - 44.1

        v = - 9.8 3

        v = - 29.4 m / s

A magnetic field of 1.7 Tesla and 7 a current are present where the reading is 2 v for 1.

The magnetic field is the area that is affected by magnetism and is located around a magnet. The magnetic field is a valuable tool for explaining the distribution of the magnetic force within and around a magnetic object in nature.

In a Hall effect Experiment, Hall probe measures

Hall voltage generated given by,

\(V_{H}\) = BI/ent

where B = Magnetic field applied

I = current generated

e = Electronic charge

n = Electron's concentration in conductor

t = thickness of conductor

Let ent = x

\(V_{H}\) = BI/x

B = 1T; I = 2A; = 1.5 μV = 1.5x10⁻⁶

1.5x10⁻⁶ = 1x2/x

x = 2/ 1.5x10⁻⁶

Now,

for  = 2 μV = 2x10-6V, I = 1.7A,

we need B,

We again use,

Vμ =BI/x

B =(2/1.5x10⁻⁶). 2 × 10⁻⁶/1.7

B = 1.7Tesla.

If you rapidly stir some raw eggs with an eggbeater, the temperature of the eggs will remain unchanged.

Humans and human ancestors have scavenged and eaten animal eggs for millions of years.

Humans in Southeast Asia had domesticated chickens and harvested their eggs for food by 1500 BCE.

The most widely consumed eggs are those of fowl, especially chickens. Eggs of other birds, including ostriches and other ratites, are eaten regularly but much less commonly than those of chickens.

People may also eat the eggs of reptiles, amphibians, and fish. Fish eggs consumed as food are known as roe or caviar.

The act of stirring will not generate any heat or cooling effect, and the temperature of the raw eggs will remain the same.

A halo around the sun or moon is often an indication that cirrostratus clouds are present.

Cirrostratus clouds are high-level clouds that form above 20,000 feet (6,000 meters). They are composed of ice crystals and have a thin, often transparent appearance. When these clouds are present, they can create a halo effect around the sun or moon.

The halo is formed when light from the sun or moon is refracted, or bent, as it passes through the ice crystals in the cirrostratus clouds. This refraction causes the light to spread out and create a ring or halo-like appearance around the sun or moon.

The presence of a halo is often an indication of thin, high-level cloud cover, typically preceding an approaching warm front or an area of moisture. It can also be a sign of changing weather conditions.

It is worth noting that halos can also be formed by other cloud types, such as altostratus or thin, wispy cirrus clouds, depending on the specific atmospheric conditions.

When you are halfway around the stadium, average speed value cannot be 0.

Average speed = Total distance travelled / Time taken.

Since you ran halfway across the stadium, a certain amount of distance has been covered. The only way the average speed can be zero is if you remained stationary over a given interval of time.

In a distance-time graph, at the halfway point in the stadium, slope is equal to zero. So, Instantaneous speed is zero. In a Velocity-time graph, at the halfway point in the stadium, slope is equal to zero. So, Instantaneous acceleration is zero. In a Velocity ( w.r.t. time )-time graph, at the halfway point in the stadium, slope is equal to zero. So, Average acceleration is zero.

Therefore, when you are halfway around the stadium, average speed value cannot be 0.

Answer:

the higher up an object is, the more potential energy it has

Explanation:

To find the rotational kinetic energy of an object with a moment of inertia of 25 kg·m² and an angular speed of 125 radians/s, you can use the formula for rotational kinetic energy:
Rotational Kinetic Energy (KE) = 0.5 × Moment of Inertia (I) × Angular Speed (ω)²

Step 1: Identify the moment of inertia (I) and angular speed (ω).
Moment of Inertia (I) = 25 kg·m²
Angular Speed (ω) = 125 radians/s

Step 2: Plug the values into the formula.
KE = 0.5 × 25 kg·m² × (125 radians/s)²

Step 3: Calculate the rotational kinetic energy.
KE = 0.5 × 25 kg·m² × 15625 (radians/s)²
KE = 12.5 kg·m² × 15625 (radians/s)²
KE = 195312.5 kg·m²·(radians/s)²

So, the rotational kinetic energy of the object is 195312.5 kg·m²·(radians/s)².

An object's mass, rather than its weight is used to indicate the amount of matter it contains because weight is defined as the amount of force due to an existing field (In most cases, gravitational field) that is experienced by the body. The weight of the same body can be different in different environments it's observed.

However, the mass of the body is the exact measure of the amount of matter contained in a body. Which is constant, regardless of the environment, or conditions the body is observed.

Hence, for real-world calculations and experimentation, the mass of the body is considered to represent the amount of matter it contains rather than its weight.

It will take 8 years for the plutonium to no longer exists.

Plutonium is extremely uncommon. On Earth, there are only traces of it. Currently, NASA only has roughly 77 pounds of plutonium-238 available. Other radioactive isotopes can also be used as a heat source for an RTG, but plutonium-238 is a particularly effective one.

It decays more rapidly as it ages due to its half-life. Therefore, even when they are not consuming any of it, their supply is gradually running out. It will only take 8 years for NASA to run out of plutonium and the prospect of finding more in time for their next deep space mission is dim.
