(1) The force of gravity between the Earth and the satellite is 8.91 * 10^6 N.

(2)  The orbital period of the satellite is 6,132 seconds i.e. 1 hour and 42 minutes.

(3) The tangential velocity required to keep the satellite in orbit is approximately 7.94 km/s.

(4) The angular velocity of the satellite is 0.0011 radians per second.

(1)  The force of gravity between two objects can be calculated using Newton's law of universal gravitation. The formula is F = (G * m1 * m2) / \(r^2\), where F is the force of gravity, G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between their centers. In this case, the mass of the Earth is much larger than the mass of the satellite, so we can consider the satellite's mass negligible compared to the Earth's mass. Plugging in the values, we get\(F = (6.67 \times 10^{-11} N m^2/kg^2) \times (5.97 \times 10^{24} kg) \times (900 kg) / (6,371,000 m)^2 = 8.91 \times 10^6 \ Newtons\)

(2) The orbital period of a satellite can be determined using Kepler's third law of planetary motion, which states that the square of the orbital period is proportional to the cube of the semi-major axis of the orbit. Since the satellite is orbiting at a radius equal to one Earth radius above the surface, the semi-major axis is the sum of the Earth's radius and the altitude of the satellite. Using the formula \(T = 2\pi \times\sqrt{(a^3 / (G \times M)}\), where T is the orbital period, a is the semi-major axis, G is the gravitational constant, and M is the mass of the Earth, we can calculate the value. Plugging in the values, we get \(T = 2\pi \times\sqrt{6,371,000}\) meters +\((6,371,000 \ m)^3 / (6.67 \times 10^{-11} N m^2/kg^2 \times 5.97 \times 10^{24} kg)\) = 6,132 seconds.

(3) The tangential velocity required to keep a satellite in orbit can be determined using the formula \(v = \sqrt{G \times M / r\) where v is the tangential velocity, G is the gravitational constant, M is the mass of the Earth, and r is the distance between the center of the Earth and the satellite. Plugging in the values, we get v = √((6.67 x 10^-11 N m^2/kg^2 * 5.97 x 10^24 kg) / \(v = \sqrt{\frac{(6.67 \times 10^{-11} N m^2/kg^2 \times 5.97 \times 10^{24} kg) }{(6,371,000 m + 6,371,000 m)}\)) = 7,906 m/sec.

(4) The angular velocity of a satellite in orbit can be calculated using the formula ω = v / r, where ω is the angular velocity, v is the tangential velocity, and r is the distance between the center of the Earth and the satellite. Plugging in the values, we get ω = 7,906 meters per second / (6,371,000 meters + 6,371,000 meters) = 0.0011 radians per second.

The final angular velocity of the playground merry-go-round after the child gets onto it is 0.337 rad/s.

To find the final angular velocity of the playground merry-go-round after a child gets onto it, we need to use the principle of conservation of angular momentum.

The initial angular momentum of the system (merry-go-round and child) is the product of its moment of inertia and its initial angular velocity. When the child gets onto it, the moment of inertia of the system increases, but its angular momentum remains conserved.

We can calculate the final moment of inertia of the system and solve for its final angular velocity. After calculating, we get that the final angular velocity is approximately 0.337 rad/s. Therefore, the final angular velocity of the playground merry-go-round after the child gets onto it is 0.337 rad/s.

Barbara's speed driving in clear weather is 30 mph and her speed driving in the thunderstorm is 11 mph.

Barbara's speed driving in clear weather is s. She drives 19 mph slower through the thunderstorm, so her speed in the thunderstorm is s - 19.

The total distance of the trip is 45 + 13 = 58 miles. And the total time for the trip is 1.5 hours.

Using the following equation to find Barbara's speed in clear weather:

distance = speed × time

45 miles = s × 1.5 hours

30 mph = s

So, Barbara's speed driving in clear weather is 30 mph.

Now find her speed in the thunderstorm by subtracting 19 mph from 30 mph:

s - 19 mph = 30 mph - 19 mph

s - 19 mph = 11 mph

Therefore, Barbara's speed driving in the thunderstorm is 11 mph.

To summarize, Barbara's speed driving in clear weather is 30 mph and her speed driving in the thunderstorm is 11 mph.

Formula(77°F − 32) × 5/9 = 25°C

Answer: The answer is C. 298 K

Explanation:

(a) The velocity of the object at time t is given by finding the derivative of y (t):

y(t) = -2t2 + t + 10dy(t)/dt

= -4t + 1

Therefore, the velocity of the object at time t is -4t + 1.

(b) The acceleration of the object at time t is given by finding the derivative of the velocity function:

dy(t)/dt = -4t + 1d2y(t)/dt2

= -4

Therefore, the acceleration of the object at time t is -4 m/s2.

(c) The ball hits the ground when y(t) = 0, so we can solve for t by setting -2t2 + t + 10 = 0 and using the quadratic formula:

t = (-b ±  (b2 - 4ac)) / (2a), where a = -2, b = 1, and c = 10.

Plugging these values into the formula, we get:

t = (-1 ±  (12 - 4(-2)(10))) / (2(-2)) = (1 ±  81) / 4

We take the negative root because the positive root corresponds to the ball reaching its maximum height before falling back down. Thus,

t = (1 - 81) / 4

= -2/4

= -0.5 s

To find the velocity of the ball at this time, we plug t = -0.5 into the velocity function we found in part

(a):v = -4t + 1

= -4(-0.5) + 1

= 3 m/s

Therefore, the velocity of the ball at the time it hits the ground is 3 m/s.

Explanation:

And the explanation would be that sound travels faster in more denser substances like water.

Since the two charges are symmetrically positioned with regard to the origin and have equal magnitudes but opposite signs, the location where the electric field is zero is at the origin.

Using the formula for the electric field produced by a point charge, we can determine the location on the x-axis where the electric field is zero:

\(E = k*q/r^2\)

where r is the distance between the point charge and the location where the electric field is being measured, q is the charge of the point charge, E is the electric field, k is Coulomb's constant, and so on. The total electric field for the two charges in this issue may be determined at any location along the x-axis using the principle of superposition. The electric field vectors produced by the two charges will cancel out at some point along the x-axis because they are symmetrically positioned with respect to the origin and have opposite signs. We may determine the electric field vectors produced by each charge at various locations along the x-axis using the formula for the electric field produced by a point charge. We can determine the overall electric field at each place by combining these vectors together. We may determine the location where the electric field is zero by charting the total electric field as a function of the x-axis position. We discover that in this instance, the two charges produce identical, opposing electric fields that cancel one another out at the origin. Because of this, the origin is where the electric field is zero.

To find the speed of a bicycle in feet per second (fps) and miles per hour (mph), we need to know the distance traveled and the time taken.

Let's assume the bicycle traveled a distance of d feet and the time taken to cover that distance is t seconds.

The speed of the bicycle in feet per second (fps) can be calculated using the formula:

\(\[ \text{Speed (fps)} = \frac{\text{Distance (feet)}}{\text{Time (seconds)}} = \frac{d}{t} \]\)

To convert the speed from feet per second (fps) to miles per hour (mph), we can use the conversion factor that 1 mile is equal to 5280 feet, and 1 hour is equal to 3600 seconds.

The speed of the bicycle in miles per hour (mph) can be calculated using the formula:

\(\[ \text{Speed (mph)} = \left(\frac{\text{Distance (feet)}}{\text{Time (seconds)}}\right) \times \left(\frac{1 \text{ mile}}{5280 \text{ feet}}\right) \times \left(\frac{3600 \text{ seconds}}{1 \text{ hour}}\right) \]\)
