A basketball player standing under the hoop shoots the ball straight up with an initial velocity of v0Part (a) What is the maxim
Mama L [17]

Answer:

Maximum height will be h=\sqrt{\frac{v_0^2}{2g}}

Explanation:

We have given initial velocity through which basketball is thrown =v_0

Acceleration due to gravity =g\  m/sec^2

At maximum height velocity will be zero

So final velocity v = 0 m /sec

According to third equation of motion v^2=u^2+2gh

0^2=v_0^2-2gh ( Negative sign is due to upward acceleration )

h=\sqrt{\frac{v_0^2}{2g}}

Describe the general characteristics of the nearest stars. (Size, luminosity, color, etc., do not include specific stars)
Darina [25.2K]

Answer: The five general characteristics of the nearest stars are the brightness, color, surface temperature, size, and mass.

Explanation:

The mass of a star can be described as being measured with our sun at 1 solar mass. One star can equal the size of our sun. There is one star named, Rigel, that is bigger than the Earths sun. Each star will vary in its density.

The size of the star, as stated above, can be the size of our sun and sometimes larger. The size is measured by solar radii.

Stars vary in their temp. They range anywhere from -273.15 degrees Celsius to 50,000 K. The temp is based on the Kelvin scale.

The stars brightness are always based on luminosity and magnitude.

The stars colors will vary and is based on the temperature of the surface of the star. Some stars are red in color, white in color, and some even have a bluish color.

a train leaves a station heading east at 50 mph from that same station a car drives north at a speed of 30mph after 3 hours how
Alecsey [184]

Answer:

d = 175 miles

Explanation:

Train is moving towards East with constant speed of 50 mph

While car is moving at speed of 30 mph

so after t = 3 hours

the distance moved by the train is given as

d_1 = vt

d_1 = (50)(3) = 150 miles

at the same time the distance moved by the car is given as

d_2 = 30(3) = 90 miles

now we know that both car and train is moving perpendicular to each other

So the distance between them after t = 3 hours is given as

d= \sqrt{d_1^2 + d_2^2}

d = \sqrt{150^2 + 90^2}

d = 175 miles

Use the law of universal gravitation to describe the relationship between you and your desk
tangare [24]
The law of gravitation states that things closer to the core of gravitation, have a larger force pulling down on them. In relation of you to your desk, you and the desk are both drawn downwards towards the center of gravity.
