1. What does the endocrine system have in common with the muscular system?

Two cylinders contain the same ideal gas and have the same volume. If the gas molecules in cylinder B have twice the average kin

ipn [44]

Hence, internal energy in cylinder B is twice than that in A.

It is given that two cylinders contain the same ideal gas and have the same volume. If the gas molecules in cylinder B have twice the average kinetic energy as those in cylinder, we need to compare internal energy.

As kinetic energy is directly proportional to temperature, internal energy is also proportional to temperature.

We can say that more the average kinetic energy, more is the internal energy.

Hence, internal energy in cylinder B is twice than that in A.

The ratio in A:B is 1:2.

A car is stopped at a traffic light. When the light turns green, the car starts from rest with an acceleration of 2.5 m/s2 . Als

erma4kov [3.2K]

Answer:

a) f = 453.3Hz

b) f = 443.1Hz

c) f = 420Hz

Explanation:

First of all we need to know the positions and velocities of both vehicles.

For the car:

Xc(-5) = 0m; Vc(-5) = 0m/s

$Xc(5) = 2.5*5^2/2=31.25m$ ; Vc(5)=2.5*5 = 12.5m/s

$Xc(10)=2.5*10^2/2=125m$ ; Vc(10)=2.5*10=25m/s

For the truck:

Xt(-5)=10*(-5) = -50m; Vt(5)=10m/s

Xt(5)=10*5 = 50m; Vt(5)=10m/s

Xt(10)=10*10=100m; Vt(10)=10m/s

Now for part a) t=-5s. The truck is behind the car, so:

$f=\frac{C}{C-Vt}*fo = 453.3Hz$

Now for part b) t=5s. The car is behind the truck, so:

$f=\frac{C+Vc}{C+Vt}*fo = 443.1Hz$

Now for part b) t=10s. The truck is behind the car, so:

$f=\frac{C-Vc}{C-Vt}*fo = 420Hz$

You need to get to class, which is 282 meters away. You can only walk in the hallway at about 2.0 m/s (if you go any faster, you

worty [1.4K]

Answer:

Time, t = 141 seconds

Explanation:

Given that,

Distance between the class and the person, d = 282 m

Speed of the person, v = 2 m/s

We need to find the time taken by the person to get to your class. Let the time taken is t. The speed of the person is given by :

$v=\dfrac{d}{t}$

$t=\dfrac{d}{v}$

$t=\dfrac{282\ m}{2\ m/s}$

t = 141 seconds

So, the time taken by the person to get to your class is 141 seconds. Hence, this is the required solution.

the oxygen you breathe is made up of two oxygen atoms bound together why is oxygen molecule but not componud

steposvetlana [31]

Having more than one atom in its molecule doesn't make
a substance a compound. It's only a compound if it has
atoms of different elements in its molecule.

Both atoms in an Oxygen molecule are the same element ... Oxygen.

5. A ball is sitting at rest on the floor. What will happen if a balanced force is applied to the ball? *

Leno4ka [110]

When the balanced force is applied on the ball It will roll away from the force.

Explanation:

A ball lies on the floor in rest. If the balanced force is applied to

the ball, the force will push away.

The forces would include gravity and the forces of air particles entering the ball from almost all directions.
And the ground is exercising the force and shifting away from the impact.
