A fox fleeing from a hunter encounters a 0.700 m tall fence and attempts to jump it. The fox jumps with an initial velocity of 7.
iris [78.8K]

Answer:0.61 m

Explanation:

Given

Initial velocity (u)=7.40 m/s

launch angle \theta =45^{\circ}

height of fence=0.7 m

Trajectory of Projectile is given by

y=x\tan \theta -\frac{gx^2}{2u^2\cos^2\theta }

For x=2.1 m  

y=2.1\tan (45)-\frac{9.8\times 2.1^2}{2\times 7.4^2\times (\cos 45)^2}

y=2.1-0.789

y=1.31 m

At x=2.1 m Y=1.31

therefore Fox clear fence by a margin =1.31-0.7=0.61 m

How many paths do the electrons have to flowlin a series circuit?
AleksandrR [38]
One path because in a series circuit it is only one path while in a parallel circuit you have 2 or more. Our houses use parallel so that is why you can turn off one light and the rest would stay on.

Compare the weight of a 5.00-kg object on Earth’s surface to the gravitational force between a 5.00-kg object that is one Earth
makkiz [27]

Answer

given,

mass of an object = 5 Kg

mass of the other object = 5.98 x 10²⁴ Kg

radius of earth = 6371 Km = 6.371 x 10⁶ m

comparison between gravitational force between two object and weight of the object.

gravitational force between two objects

   F = \dfrac{Gm_1m_2}{r^2}

   F = \dfrac{6.67 \times 10^{-11}\times 5 \times 5.98 \times 10^{24}}{(6.371 \times 10^6)^2}

      F = 49.134 N

weight of the object on the earth surface

  F = m g

  F = 5 x 9.81

  F = 49.05 N

From the above two calculation we can conclude that gravitational force is approximately equal to weight of the body.

Verify the following equations:3² ×3³=243
e-lub [12.9K]

The equations are 3^2\times \:3^3=243

What is the formula used to calculate the equation?

To solve the equation using the formula of x^{2} * x^{3}

Find the equation by using formula.

On comparing with 3^2\times \:3^3=243

We get,  =(3*3)(3*3*3)

         =9*27

  Hence the equation is   =243
