"The direction of force that the branch exerts on the chimpanzee is towards the ground.

The force of the branch on the chimpanzee is the gravitational force. It acts downwards on the chimpanzee, and hence the direction of the force is downwards towards the earth. Let's assume that the chimpanzee is hanging on a branch of a tree and is stationary. Then, the gravitational force, also known as the weight of the chimpanzee, acts downwards on the chimpanzee. The weight of the chimpanzee is equal to the mass of the chimpanzee multiplied by the acceleration due to gravity.The force exerted by the branch on the chimpanzee is an equal and opposite reaction to the force exerted by the chimpanzee on the branch, according to Newton's Third Law of Motion. Therefore, the direction of the force exerted by the branch on the chimpanzee is towards the ground.

A bicycle of mass 7 kg is being ridden by a bicyclist of mass 57 kg at a speed of 5.4 m/s. The total momentum of the bike and bicyclist is 342 kg m/s.

Momentum is defined as the product of the mass and velocity of an object. Momentum is a vector quantity, which means it has both magnitude and direction.

Momentum = mass × velocity

Momentum is represented by the letter p and has the SI unit of kilogram meters per second (kg m/s).

Bicycle mass (m) = 7 kg

Bicyclist mass (M) = 57 kg

Speed (v) = 5.4 m/s

To calculate the total momentum of the bike and bicyclist, we need to first find the momentum of each separately and then add them together.

Using the formula for momentum:

Momentum of bicycle = mass × velocity

= 7 kg × 5.4 m/s= 37.8 kg m/s

Momentum of bicyclist = mass × velocity

= 57 kg × 5.4 m/s

= 308.4 kg m/s

Total momentum = momentum of bicycle + momentum of bicyclist

= 37.8 kg m/s + 308.4 kg m/s

= 346.2 kg m/s

≈ 342 kg m/s (rounded to the nearest whole number)

The correct answer is: a. A + B. Two waves meet at a time when one has the instantaneous amplitude A and the other has the instantaneous amplitude B.

When two waves meet, the resulting combined amplitude depends on the properties of the waves and their relative phase. The principle of superposition states that when two waves overlap, the displacements of the waves at each point add algebraically.

In the case where one wave has an instantaneous amplitude A and the other wave has an instantaneous amplitude B, the combined amplitude at that particular time will be the sum of the amplitudes of the two waves.

Therefore, the correct answer is: a. A + B

According to the Ideal Gas Law, the value of rho is equal to the density of the gas.

The Ideal Gas Law states the relationship between pressure, volume, temperature, and the number of moles of a gas. It states that the ratio of pressure multiplied by the volume of a gas is equal to the number of moles of the gas multiplied by the universal gas constant and the temperature of the gas.

This can be derived by rearranging the equation to solve for rho.

Step 1: Start with the Ideal Gas Law equation: p = rho r t
Step 2: Rearrange the equation to isolate rho on one side: rho = p / (r t)
Step 3: Substitute the given values for p, r, and t into the equation: rho = p / (r t)

Therefore, the value of rho is equal to the pressure divided by the product of the gas constant and the temperature.

Explanation:

the answer is in the above image

Given:

mass of first ball, m1 = 35g

mass of second ball, m2 = 75g

velocity of first ball before collision, u1 = 9m/s

velocity of second ball before collision, u2 = -7m/s

velocity of first ball after collision, v1 = -15m/s

velocity of second ball after collision, v2 = ? (To Find)

Now it is given that there is no net force on the system of two balls

according to the Law of Conservation of Momentum so, here momentum is constant before and after collision:

P1 = P2

m1u1 + m2u2 = m1v1 + m2v2

35g*9m/s + 75g*(-7m/s) = 35g*(-15m/s) + 75g*v2

v2 = (35g*9m/s + 75g*(-7m/s) - 35g*(-15m/s))/75g

v2 = 4.2m/s

therefore, the velocity of second ball after collision is 4.2m/s

As a result, the equation of the law of conservation of momentum is as follows: m1 u1 + m2 u2 represents the total momentum of particles A and B before the collision, and m1 v1 + m2 v2 represents the total momentum of particles A and B after the collision.

Momentum. If the mass of an object is m and it has a velocity v, then the momentum of the object is defined to be its mass multiplied by its velocity. momentum = mv. Momentum has both magnitude and direction and thus is a vector quantity. The units of momentum are kg m s−1 or newton seconds, N s.

To determine the thickness of the subbase course, we can use the AASHTO (American Association of State Highway and Transportation Officials) design method.

The formula for calculating the thickness of the subbase course is as follows:

Subbase Thickness = (SN - (a2 × Base Thickness)) / MR

First, we need to convert all the thickness values to the same units. Let's use inches for consistency.

Subbase Thickness = (SN - (a2 × Base Thickness)) / (MR / 1000)

Subbase Thickness = (6.3 - (0.13 × 6)) / (14,000 / 1000)

= (6.3 - 0.78) / 14

= 5.52 / 14

Subbase Thickness ≈ 0.394 inches

Very little energy is dissipated in the thick connecting wires.

Resistance is inversely proportional to wire length, so less energy is dissipated through the wire and more energy is dissipated through the bulb. The resistance of the wires is low enough that there is not enough voltage drop across the wires so there is no noticeable voltage difference across the bulb.

The more bulbs you connect in series the brighter or brighter the bulb. The light is dimmer because less current flows through each bulb. This is because adding more bulbs in a series means adding more resistance. In a parallel circuit, current flows through separate branches. If another branch is added with another bulb, the current will have to follow an additional path. However the battery produces a constant voltage, so the current through the original lamp and its brightness remain unchanged.

The tides on Earth are primarily caused by the gravitational pull of the Moon. The absence of the Moon would have a significant impact on the tides and the entire Earth's ecosystem.

Tides are created by the gravitational force of the Moon acting on the water in the oceans. As the Moon orbits around the Earth, its gravitational force causes the water to bulge on the side of the Earth closest to the Moon, creating a high tide.

Without the Moon's gravitational pull, there would still be some tides on Earth, but they would be much smaller than they are currently. The Sun also exerts a gravitational pull on the Earth, but it is much weaker than the Moon's.

The absence of the Moon would also affect other aspects of Earth's ecosystem, such as the migration patterns of some animals, and the stability of the Earth's axial tilt, which would be more prone to fluctuations. The Moon also plays a role in stabilizing the Earth's orbit around the Sun, so the absence of the Moon could cause changes in the Earth's climate and weather patterns over time.
