The orbital radius of the satellite orbiting planet Earth at the given linear speed is 26,000 km.
Orbital radius of the planetThe orbital radius of the planet is the distance of the planet from the center of the Earth. The orbital radius of the planet is calculated as follows;
[tex]v = \sqrt{\frac{GM}{r} }[/tex]
where;
M is mass of EarthG is gravitational constantr is the orbital radiusr = GM/v²
r = (6.67 x 10⁻¹¹ x 5.97 x 10²⁴)/(3,914²)
r = 2.6 x 10⁷ m
r = 26,000 km
Thus, the orbital radius of the planet is 26,000 km.

Question 1: What is the before image showing?
Question 2: What is the after image showing?
Answer:
the after image is showing precipitation. i dont know what the before image is though.
Explanation:
In some amazing situations, people have survived falling large distances when the surface they land on is soft enough. During a traverse of Eiger's infamous Nordvand, mountaineer Carlos Ragone's rock anchor gave way and he plummeted 515 feet to land in snow. Amazingly, he suffered only a few bruises and a wrenched shoulder. Assuming that his impact left a hole in the snow 3.5 ft deep, estimate his average acceleration as he slowed to a stop (that is while he was impacting the snow). Pick a coordinate system where down is positive.

Example Compute the capacitance of a parallel-plate capacitor with plates 10cm by 20cm, separation of 5mm, and a mica dielectric.
Answer:
Explanation:
Mica dielectric constant (k) is approximately 3. The distance between the plates is 5 mm = [tex]5\times10^{-3}[/tex] m = d and the area of each plate is[tex]A = 0.1\times 0.2=2\times 10^{-2} m^{2}[/tex]. So, the capacitance of that capacitor is:
[tex]C=\frac{\epsilon_{0}kA}{d}=\frac{(8.85\times10^{-12})(3)(2\times10^{-2}}{5\times10^{-3}}=10.62\times10^{-11} =1.062\times10^{-10} F[/tex]
or approximately 0.106 nF.

10. The speed of a transverse wave is 15 m/s. The frequency of the wave is 2.5 Hz.
What is the wavelength? *
Answer:
Wavelength = 6m
Explanation:
Given that,
→ Transverse wave = 15 m/s
→ Frequency = 2.5 Hz
Then the required wavelength is,
→ Transverse wave ÷ Frequency
→ 15 ÷ 2.5
→ 15/2.5 = 6m
Hence, the wavelength is 6m.

The blood pressure of human body is greater at the feet than at the brain. why?give reason
Answer:
Gravity stronger closer to the core of the earth
Explanation:
The gravity applied to the feet is stronger than to the upper part of the body for example the brain because of the distance it is between the body part and the core of the earth where the gravity force is pulling towards. Even though the difference between the gravity force between the brain and the feet is minimal it is still a greater force at the feet than at the brain
The graph in the figure shows the position of a particle as it travels along the x-axis. What is the magnitude of the instantaneous velocity of the particle when t=1.0 s?
Answer:
pls first attach the fig.
The graph in the figure shows the position of a particle as it travels along the x-axis. The magnitude of the average speed of the particle between t = 1.0 s and t = 4.0 s is 1.3 m / s. Therefore, option B is correct.
What do you mean by average speed ?The term average speed is defined as the total distance traveled by the object in a particular time interval.
In the kinematics studies the movement of bodies, give the relationships between position, velocity and acceleration. In the special case that the acceleration is zero the motion is known as uniform motion.
v = Δ x / Δt
Where v is the velocity, Δx is the position variation and Δt is the time variation in the analyzed interval.
Therefore,
v = 2.0 - ( - 2.0 ) / 4.0 - 1.0
v = 1.33 m / s
Thus, The magnitude of the average speed of the particle between t = 1.0 s and t = 4.0 s is 1.3 m / s, option B is correct.

What is the net force acting on a car cruising at a constant velocity of 70 km/h (a) on a level road, (b) on an uphill road?
The net force on the car for either case will be zero, since the car is moving at a constant velocity.
Net force on the car
The net force on the car is the sum of all the forces acting on the car.
∑F = ma
When the car is on a level roadWhen the car is on a level road, the only two forces acting on the car is the applied force and frictional force of the road.
F - Ff = 0
The net force will be zero, since the car is moving at a constant velocity.
When the car is on uphillThe forces acting on the car at the uphill is the applied force, weight of the car acting downwards and the frictional force acting opposite direction.

A. electrical force and frictional force
B. electrical force and magnetic force
C. frictional force and gravitational force
D. magnetic force and gravitational force
Answer:
It's B (electrical force and magnetic force) I just took the test.
The two forces can Danielle's device produce will be an electrical force and magnetic force. Daniel forms a coil resulting in both forces.
What is electric force?Electric Force on the particle is defined as the application of the force field of one particle on another particle. It is a type of virtual force. it is the ratio of voltage to the distance between them.
Danielle took an iron nail and wrapped thin copper wire around it, then connected the ends of the copper wire to a battery.
A coil of wire that carries an electric current is a solenoid. A solenoid is an electromagnet formed by a helical coil of wire. Which generates a magnetic field when an electric current is passed through the coil.
A solenoid is a form of coil that produces a magnetic field when the electric current is passed through it. A solenoid is created when a conductive wire is used to make a loop.

kg toddler at the very bottom of the ferris wheel?
The normal force of the ferris wheel on a 10kg toddler at the very bottom of the ferris wheel is 102.41 N.
Centripetal force of the Ferris wheelThe normal force of the ferris wheel on a 10kg toddler at the very bottom of the ferris wheel is calculated as follows;
Fn = Fc + mg
Fn = mω²r + mg
Fn = m(ω²r + g)
where;
ω is the angular speed = 1 rev/30 s = 2π/30 s = 0.21 rad/sFn = 10(0.21² x 10 + 9.8)
Fn = 102.41 N
