What happened to a apple's weigh as the plane rose up toward the sky?

Answers

Okay, I don't know if this question is supposed to be a trick question or not. The weight of the apple does not change as the plane travels up the atmosphere, but the MASS changes. Weight doesn't change no matter what environment you're in, but the mass changes in different environments. In this case, the weight is constant but the mass is decreasing as you go higher up.

A motor with a power of 7.0 × 104 watts lifts a loaded elevator to a height of 20.00 meters for 40 seconds. What is the force exerted by the motor on the elevator?

Answers

Answer:

$1.4\cdot 10^5 N$

Explanation:

First of all, we can find the work done as follows:

$W=Pt$

where P is the power and t is the time taken. In this problem, $P=7.0\cdot 10^4 W$ and $t=40 s$ , so the work done is

$W=Pt=(7.0\cdot 10^4 W)(40 s)=2.8\cdot 10^6 J$

The work done is equal to the force applied F times the displacement d:

$W=Fd$

since we know d=20.0 meters, we can re-arrange the equation to find the force exerted:

$F=(W)/(d)=(2.8\cdot 10^6 J)/(20.0 m)=1.4\cdot 10^5 N$

Maria throws an apple vertically upward from a height of 1.3 m with an initial velocity of +2.8 m/s. Will the apple reach a friend in a tree house 5.9 m above the ground? The acceleration due to gravity is 9.81 m/s 21. No, the apple will reach 5.27136 m below the tree house2. Yes, the apple will reach 5.27136 m above the tree house3. No, the apple will reach 1.43117 m below the tree house4. No, the apple will reach 1.5289 m below5. Yes, the apple will reach 1.5289 m above the tree house6. Yes, the apple will reach 1.43117 m above the tree house

Answers

Answer:

No, the apple will reach 4.20041 m below the tree house.

Explanation:

t = Time taken

u = Initial velocity = 2.8 m/s

v = Final velocity = 0

s = Displacement

g = Acceleration due to gravity = -9.81 m/s² = a (negative as it is going up)

Equation of motion

$v^2-u^2=2as\n\Rightarrow s=(v^2-u^2)/(2a)\n\Rightarrow s=(0^2-2.8^2)/(2* -9.81)\n\Rightarrow s=0.39959\ m$

The height to which the apple above the point of release will reach is 0.39959 m

From the ground the distance will be 1.3+0.39959 = 1.69959 m

Distance from the tree house = 5.9-1.69959 = 4.20041 m

No, the apple will reach 4.20041 m below the tree house.

The values in the option do not reflect the answer.

Final answer:

The apple will not reach the friend in the tree house as it will only reach a height of approximately 1.527 m.

Explanation:

To determine whether the apple will reach a friend in a tree house 5.9 m above the ground, we can use the equations of motion. Since the apple is thrown vertically upward, it will experience a negative acceleration due to gravity. Using the equation h = vo*t + (1/2)*a*t^2, where h is the final height, vo is the initial velocity, a is the acceleration, and t is the time, we can calculate the time it takes for the apple to reach a height of 5.9 m. Plugging in the values, we get:

5.9 = 2.8*t + (1/2)*(-9.81)*t^2

Simplifying the equation, we have:

-4.905*t^2 + 2.8*t - 5.9 = 0

Using the quadratic formula, we can solve for t. The quadratic formula is t = (-b ± sqrt(b^2 - 4ac)) / (2a), where a = -4.905, b = 2.8, and c = -5.9.

Plugging in the values, we get:

t = (-2.8 ± sqrt(2.8^2 - 4*(-4.905)*(-5.9))) / (2*(-4.905))

After evaluating the formula, we find that the apple will take approximately 1.527 seconds to reach a height of 5.9 m. Since the apple continues to rise after reaching this height, it will not reach the friend in the tree house.
