a dog is running at 5.5 m/s then comes to a complete stop in 1.5 seconds. What is the dogs acceleration?
The dog's acceleration running at 5.5 m/s then comes to a complete stop in 1.5 seconds is 8.25m/s²
HOW TO CALCULATE ACCELERATION:
The acceleration of a moving object can be calculated by multiplying the velocity of the object by the time taken. That is;Acceleration (m/s²) = speed (m/s) × time (s)According to this question, a dog is running at 5.5 m/s then comes to a complete stop in 1.5 seconds. The acceleration can be calculated as follows:Acceleration = 5.5 × 1.5Acceleration = 8.25m/s²Therefore, the dog's acceleration running at 5.5 m/s then comes to a complete stop in 1.5 seconds is 8.25m/s².Learn more at: https://brainly.com/question/19573976?referrer=searchResults

why is the saturated lapse rate less than the dry adiabatic lapse rate?
Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
Lifting a saturated package causes it to expand and cool, resulting in vapour condensation. Condensation will release latent heat, partially counteracting the cooling. As a result, a saturated parcel's adiabatic lapse rate is smaller than an unsaturated parcel's.
Because moist air ascending condenses off its water vapour, the moist adiabatic lapse rate is lower than the dry adiabatic lapse rate (once saturation is attained). The air is considered to be saturated when the dew point temperature and air temperature are identical.

At a race car driving event, a staff member notices that the skid marks left by the race car are
10.99 m long as it comes to a stop. The very experienced staff member knows that the
deceleration of a car when skidding is -42.61 m/s2. What can the staff member estimate for
the original speed of the race car if it came to a stop during the skid?
A car that experiences a deceleration of -41.62 m/s² and comes to a stop after 10.99 m has an initial velocity of 30.60 m/s.
A car experiences a deceleration (a) of -41.62 m/s² and comes to a stop (final velocity = v = 0 m/s) after 10.99 m (s).
We can calculate the initial velocity of the car (u) using the following kinematic equation.
[tex]v^{2} = u^{2} + 2as\\\\u = \sqrt[]{v^{2}-2as} = \sqrt[]{(0m/s)^{2}-2(-42.61m/s^{2} )(10.99m)} = 30.60m/s[/tex]

Imagine that you are going to make an exercise routine. If your goal was to develop your health rather than one specific improvement, what should be in your plan?
A.
a focus on the benefits of stretching
B.
a variety of aerobic and anaerobic exercises
C.
a single exercise with increasing intensity
D.
an exercise that you have never tried before
PLEASE NO LINKS
Answer:
c
Explanation:
If the goal of the exercise routine is to develop overall health rather than focusing on one specific improvement, a well-rounded approach that addresses various aspects of fitness would be ideal.
This would involve a combination of different types of exercises to promote cardiovascular health, muscular strength, flexibility, and overall well-being. From the given options, the best choices would be:
B. A variety of aerobic and anaerobic exercises: This option is important because it incorporates both cardiovascular exercises (aerobic) and strength-building exercises (anaerobic), ensuring a balanced approach to fitness.
A. A focus on the benefits of stretching: Stretching is important for maintaining flexibility and preventing injuries. Incorporating stretching exercises, such as static and dynamic stretches, can contribute to overall health and mobility.
D. An exercise that you have never tried before: While not as essential as the first two options, trying new exercises can add variety and excitement to your routine. It can also engage different muscle groups and challenge your body in new ways.
C. A single exercise with increasing intensity: While progressively increasing the intensity of a single exercise can be part of a fitness plan, focusing solely on a single exercise may not provide the diverse benefits that a combination of exercises can offer. Variety is key to a well-rounded fitness routine.

Suppose two ships start from point B and travel west. One ship travels at an average velocity of 35 km/h for 2.2 h. Another ship travels at an average velocity of 26 km/h for
2.5 h. What is the final position of each ship?
Answer:
Another ship travels at an average velocity of 26 km/h for
Explanation:
Ship one will cover a distance of 77 km after 2.2 hours and ship two will cover a distance of 65 km after 2.5 hours.
What are average speed and velocity?The average speed of an object is the average distance it covers in a given length of time. The scalar number reflects the average speed. Direction can be replaced with magnitude.
[tex]Average\ speed=Total\ distance/Total\ time[/tex]
Average velocity is a vector quantity. The change in position or displacement divided by the periods of time during which the change occurs is known as average velocity. Depending on how the displacement has been adjusted, the average velocity could be either positive or negative. Meters per second (m/s), or average velocity, is the SI measure for speed.
[tex]Average\ Velocity=Total\ displacement/Total\ time[/tex]
According to the question,
Ship one has an average velocity of 35 km/h for 2.2 hours.
So, total distance covered by ship one = 35 × 2.2 = 77 km.
Ship one has an average velocity of 26 km/h for 2.5 hours.
So, total distance covered by ship one = 26 × 2.5 = 65 km
Hence, the distance covered by ship one is 77 km and ship two will cover 65 km.

In induction, what charge does a neutral substance gain compared to the object brought near it?
Explanation:
In induction, what charge does a neutral substance gain compared to the object brought near it?
The neutral object gains the same type of charge as the object that touched it because the electrons move from one object to the other (Figure 10.16). Induction is the movement of electrons within a substance caused by a nearby charged object, without direct contact between the substance and the object.
The charge gained by the neutral substance, gained compared to the object brought near it, had the same kind of charge that was present when it touched it.
What is induction?The alteration of the distribution of electric charge on a substance is caused by the effect of induction. A negatively charged object brought close to an electrically neutral object causes a positive charge on the near side and a negative charge on the far side of the neutral object as a result of the electric force between charged particles that make up materials.
This very little polarization, or separation of charge, lessens the electric field inside the dielectric.
Because the electrons go from one thing into the next, the neutral object acquires the same kind of charge that was present when it touched it. Lacking physical touch, induction is the movement of electrons within a substance as a result of a nearby charged item.
