an object is accelerating if there is a change in speed and which factor?
Answers
Answer:
Speed and direction.
Explanation:
When an object accelerates, its velocity changes. Velocity is often thought of as an object's speed with a direction. Thus, objects accelerating are either speeding up, slowing down or changing directions.

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
Answers
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.

what observations about disks of dusty material around young stars suggest that planets may be forming in such disks?
Answers
Planets may be forming from dust disks because these disks are filled with completely empty lanes.
We can arrive at this answer because:
The existence of empty lanes allows the dust disks to transform into many different materials, including new planets.In this case, there is a cooling of the dust disk, which cools more and more over time.This cooling causes all the particles in that disk to clot.Coagulation increases the density of the particles and if they are dense enough they can form escape accretions.Escape accretions allow for the formation of planetary embryos, which may form planets in the future.

Using the formula, S=ut+½at²

22=½.a.5²
a=44/25 = 1.76m/s².
Therefore, net force = work done = ma = 48×1.76 = 84.48N.
therefore, power = work done/time = 84.48/5 = 16.896W.

from the base of the tower does the projectile hit the ground?
Answers
Hi there!
We can begin by solving for the time it takes the projectile to reach the ground.
Use the equation:
[tex]t = \sqrt{\frac{2h}{g}}[/tex]
Plug in the given height:
[tex]t = \sqrt{\frac{2(357)}{9.8}} = 8.536 s[/tex]
Use the equation:
d = vt, to solve for the horizontal distance:
d = (54)(8.536) = 460.944 m

why does lowered air pressure allow water to boil at room temperature
Answers
Answer:
As ambient air pressure decreases, molecules evaporating from a boiling liquid meet less resistance from air molecules and enter the air more easily. Because the vapor pressure can be reduced, the temperature needed to boil the liquid is also reduced.

Less force pushes down on the liquid, making it easier for gas to escape.

A spacecraft orbiting a planet at an altitude of 120 km releases a satellite that falls towards the surface. The planet has a mass of 5.2 x 10^23 kg and a radius of 2800 km. What is the acceleration of the satellite?
Answers
Answer:
Consider a satellite with mass Msat orbiting a central body with a mass of mass MCentral. The central body could be a planet, the sun or some other large mass capable of causing sufficient acceleration on a less massive nearby object. If the satellite moves in circular motion, then the net centripetal force acting upon this orbiting satellite is given by the relationship
Fnet = ( Msat • v2 ) / R
Explanation:
The acceleration of the satellite released from a spacecraft orbiting a planet at an altitude of 120 km and the planet has a mass of 5.2 x 10^23 kg and a radius of 2800 km is 4.426 * [tex]10^6[/tex] [tex]m/s^2[/tex].
What is acceleration?
The term "acceleration" refers to the rate and direction at which velocity varies over time. Acceleration is the change in direction or speed of an object or points moving ahead. The frequent change in direction causes motion on a circle to rise even when the speed remains constant.
For all other motions, these effects increase the acceleration. A vector quantity, acceleration, is something that has both a magnitude and a direction. Velocity is a vector quantity as well.
Given:
The altitude of the spacecraft, h = 120 km,
The mass of the planet, m = [tex]5.2 * 10^{23}[/tex] kg,
The radius of the planet, r = 2800 km.
Calculate the acceleration by the formula given below,
A = [tex]G* m /r^2[/tex]
Here, A is the acceleration, G is the gravitational constant,
Substitute the values,
A = 6.674 * [tex]10^{-11}[/tex] *5.2 * [tex]10^{23}[/tex] / [tex]2800^2[/tex]
A = 4.426 * [tex]10^6[/tex] [tex]m/s^2[/tex]
Therefore, the acceleration of the satellite is 4.426 * [tex]10^6[/tex] [tex]m/s^2[/tex]

A ball accelerates uniformly at +4.0 m/s2
If the ball was initially moving a +0.20 m/s and the average velocity was +4.2 m/s, then how long will it take it to reach the final velocity?
Answers
It will take 1 second to reach the final velocity
Acceleration of a body is the change in velocity of the body with respect to time. This is mathematically represented as;
[tex]a=\frac{v-u}{t}[/tex]
Given the following parameters
a = +4.0 m/s²
u = +0.20m/s
v = +4.2m/s
Substitute the given parameters into the formula to get the time "t"
[tex]4=\frac{4.2-0.2}{t}\\4t=4.2-0.2\\4t=4.0\\t=\frac{4}{4}\\t=1sec[/tex]
This shows that it will take 1 second to reach the final velocity
