Answer:

The answer is 5 a

Explanation:

First subtract two from ten then because of the friction. Next divide 40 kg by 8 N. When you do that you will get 5 for acceleration. Always make sure that you put the symbol next to your answer.

The velocity is defined as the rate of change of displacement per unit time and the unit of velocity is m/s. Velocity is of two types and they are average velocity and instantaneous velocity.

A) From the given graph, object B traveled faster when compared with object A. Because the speed of object B increases gradually with time whereas the speed of object A decreases with time. Hence, object B travels faster.

B)The velocity increases with time 2s to 4s. The velocity is defined as the rate of change displacement by time taken. v = Δx/Δt, where Δx is the change in displacement and Δt is the time taken. Δx = final.dis - initial dis = 0-(-4) = 0+4 = 4 m. Δt = final.time-ini.time = 4-2 = 2s. Thus, the velocity v = 4/2 = 2 m/s. Hence, the velocity increases gradually.

C) The acceleration is defined as the rate of change of velocity per unit time. From the given graph, the change in velocity does not change, and hence Δv = 0. Acceleration a = Δv/Δt = 0. Thus, the acceleration of the object is zero.

D) Acceleration (a) is the rate of velocity per unit time and the unit of velocity is m/s². Acceleration (a) = Δv/Δt, where Δv is the change in velocity. Δv = final.velocity - initial.velocity = 8-(-2) = 8+2 = 10 m/s. Δt = final. time-initial. time = 7-3 = 4s. a = 10/4=2.5m/s². Hence, the acceleration is 2.5m/s².

E) Force is the product of mass and acceleration. From the given, the force moves in both forward and backward directions, and hence, force is a vector quantity. F(net) = F₁+F₂=18 - 6 = 12N. The mass of the cart is 2kg.

F = ma

a = F/m

  = 12/2

  = 6 m/s²

Thus, the acceleration of the cart with a mass of 2kg is 6 m.s⁻².

The amplitude of a wave is directly related to the energy carried by the wave. This is because the amplitude of a wave is defined as the distance between the rest position of the wave and its highest or lowest point.

As the amplitude of a wave increases, the energy carried by the wave also increases .In the animation, we can see that as the amplitude of the wave increases, the height of the wave increases as well. This means that more energy is being transferred through the wave. Conversely, when the amplitude of the wave decreases, the height of the wave decreases and the energy carried by the wave decreases as well.

This relationship between amplitude and energy can be further illustrated by considering sound waves. A louder sound corresponds to a higher amplitude sound wave, which carries more energy. Similarly, a quieter sound corresponds to a lower amplitude sound wave, which carries less energy.

It is a true statement that a strong force occurs because neutrons work to keep protons in place inside the nucleus of an atom so the protons do not push each other out of the atom.

The nucleus contains nucleons. These nucleons are protons and neutrons. The neutrons have no charge while the protons are positively charged.

As the number of protons in the nucleus increase, repulsion between like charged particles continues to increase.

This is mitigated by the strong attractive force provided by neutrons. This force counteracts the repulsion between protons thereby keeping the nucleons of an atom together.

The loss of body heat involving the transfer of heat from the surface of one object to the surface of another without physical contact is called radiation.

Radiation is a type of heat transfer that occurs through electromagnetic waves. In the case of the human body, radiation can occur when the body is in close proximity to colder objects or surfaces. This type of heat loss can happen even when the air temperature is relatively warm. For example, on a sunny day, a person may feel cooler when standing in the shade because the body is losing heat through radiation to the cooler shaded area.
It is important to be aware of radiation as a potential cause of heat loss and take appropriate measures to stay warm in cold environments. Wearing protective clothing and staying in warm areas can help reduce the amount of heat lost through radiation.
In summary, radiation is the transfer of heat from the surface of one object to the surface of another without physical contact and can result in the loss of body heat.

Mexican food has become popular worldwide because of its unique flavors and deliciousness. When eating Mexican food, people have different preferences on where to eat, and some prefer to order a salsa.

A survey on people's favorite Mexican restaurant and their preference for ordering salsa may yield biased results due to various reasons. Biased results are those that are not accurate and do not reflect the actual views of the respondents. Therefore, some of the reasons that may cause the survey to yield biased results are as follows: Sampling errors: A survey may be biased if the sampling of participants is not done well. A biased sampling may involve picking people who have similar views, leading to false results.

The two situations that could be true about the motion of the car are: "The car is moving at a fixed speed and direction.", and "The car is parked."

If the net force on a car is zero in both the horizontal and vertical directions, then according to Newton's First Law of Motion, the car will continue to move at a constant velocity (including a velocity of zero if it is parked). In other words, the car will maintain its current state of motion unless acted upon by an external force.

The other options are not true because:

If the car is speeding up onto the highway, then there must be a net force in the forward direction (horizontal direction) acting on the car. So, the net force is not zero in the horizontal direction.

If the car is braking (slowing down), then there must be a net force in the opposite direction of motion (horizontal direction) acting on the car. So, the net force is not zero in the horizontal direction.

If the car is being struck by another car, then there is an external force acting on the car, and So, the net force is not zero.

Hence, The following two scenarios about the motion of the car could apply: "The car is moving at a fixed speed and direction.", and "The car is parked."

Arge-scale structure in the universe has probably been shaped primarily by the gravity of cluster matter is true.

The large-scale structure of the universe, such as the formation of galaxy clusters, superclusters, and cosmic filaments, is primarily shaped by the gravitational interactions of matter. Gravity acts as the dominant force in pulling matter together over cosmic scales, leading to the formation of structures on the largest observable scales in the universe. The gravitational attraction between matter, including dark matter, drives the clustering of galaxies into groups and clusters, which in turn contributes to the overall structure of the universe. Other factors, such as the expansion of the universe and the influence of dark energy, also play a role but gravity remains the primary force shaping the large-scale structure of the universe.
