Answer:

light travels slowest in diamond

Explanation:

The higher the index of refraction is, the slower the speed of light is. The indexes of refraction for diamond, air, and glass are, respectively, 2.42, 1.00, and approximately 1.50, depending upon the composition of the glass. Light travels slowest in diamonds.

The  friction between the tires and the road causes loss of energy in the form of heat-energy.

The term kinetic energy refers to the energy of an object that is in motion. The pasengers that are sitting at a point possess potential energy. If the bus stops suddenly, the potential energy of the passengers is converted to kinetic energy as they move forward.

Since friction causes loss of energy, the  friction between the tires and the road causes looss of energy in the form of heat-energy.

Answer:

Two objects are moving in opposite direction on a straight line. After collision, they stick together and move with common velocity

The total momentum of a colliding system is constant always. Therefore, by using this concept, the final velocity of the coupled mass will be 3.7 m/s.

Momentum of an object is the ability of an object to bring the force applied to make a maximum displacement. It is the product of its mass and velocity. Momentum is a vector quantity. It have both magnitude and direction.

The momentum in a collision is conserved. Thus total initial momentum is equal to the final momentum. Let m1 and m2 be the colliding masses and the u and v be the initial and final velocity.

Then, m1 u1 + m2u2 = (m1 + m2)v for a coupled mass after collision.

then final velocity v =  ( m1 u1 + m2u2 )/ (m1 + m2)

Apply the given values in the equation as follows:

v = (0.25 kg ×3.4m/s + 0.45 kg× 3.9 m/s)) (0.45 + 0.25) = 3.7 m/s

Therefore, the final velocity of the coupled masses after collision is  3.7 m/s.

Answer:

Around 20 watts, or 19.4W exactly

Explanation:

to calculate the power in a time frame you use
Joules/Time(Seconds) = W (your power)

So, we take 3500 joules / 3min (180sec)
3500/180 = 19.4W, if your question asks you to round up/down, round up to 20W of power! good luck!

Answer:

Copper

Explanation:

Capacitance is directly proportional to dielectric constant

Aluminium and zinc are highly reactive and have high dielectric contact.

Copper has less dielectric constant hence capacitance will decrease

Answer:

a1 = (V2 - V1) / 1 s = 3.75 m/s^2

a2 = (V2 - V1) / (t2 - t1) = (7.5 - 3.75) / 1 s = 3.75 m/s^2

a3 = (V2 - V1) / (t2 - t1) = (7.5 - 3.75) / 1 s = 3.75 m/s^2

A) a = (a1 + a2 + a3) / 3 = 3.75 m/s^2

v = a (t2 - t1)

B) after    1 sec    v = 3.75 m / sec^2 * 1 sec = 3.75 m/s

    after   2 sec     v = v0 + a t = 3.75 m/s + 3.75 m/s^2 * 1 s = 7.5 m/s

Answer:

44 1/3 cm

Explanation:

The cube has an edge length of ∛0.027 m = 0.3 m, so a center of mass (CoM) 15 cm above the floor.

The sphere's center of mass is 40 cm above the top of the cube, so is 70 cm above the floor. The weighted average of the CoM locations is ...

 ((15 cm)(0.700 kg) +(70 cm)(0.800 kg))/(0.700 kg +0.800 kg)

 = (10.5 kg·cm +56 kg·cm)/(1.500 kg) = 44.333... cm

The center of mass of the two-object system is 44 1/3 cm above the floor.
