An aircraft traveling at 600km/h accelerates steadily at 10km/h per second. Taking the speed of sounds as 1100km/h at the aircraft's altitude, how long will it take to reach the sound barrier.
Answer:
V2 - V1 = a t for uniformly accelerated motion
t = (V2 - V1) / a = (1100 -600) km/hr / 10 km/hr/sec
t = 500 / 10 sec = 50 sec

table at the same speed?
Why?
Answer: a bowling ball
Explanation: a baseball doesn’t need as much kinetic energy because it’s smaller
If a bowling ball is rolling at the same speed as a small baseball then since the bowling ball is bigger it has more kinetic energy

if a person with a mass of 70kg is standing on scale in an elevator when the cable snaps, what will the reading on the scale be during free-fall?
Answer:
The reading will be the same.
Explanation:
Mass does not depend upon anything and it remains the same anywhere. What changes is the weight of the body because it depends upon gravity and is different at different places.
Giving me the brainest will be helpful.
The reading on the scale during free-fall will be the same. reading on the scale is independent of the external environment.
What is a weighing scale?A weighing scale known as a balance is a device used to quantify weight or mass. The classic scale is made up of two plates or bowls that are suspended at equal distances from a fulcrum.
A person with a mass of 70kg is standing on a scale in an elevator suddenly the cable snaps, The reading on the scale during free-fall will be the same as the initial elevator condition.
Hence the reading on the scale during free-fall will be the same. reading on the scale is independent of the external environment.

Explanation:
Three forces act simultaneously on poin J. One force is 10.0 N north; the second is 15.0 N west; the third is 15.0 N 30.0° east of north. Determine the magnitude and direction of the resultant force.
The magnitude and direction of the resultant force are 10.0N and 101.36⁰
The sum of force along the force horizontal is expressed as:
[tex]\sum F_x=-15.0N+15cos30\\\sum F_x = -15.0N + 12.99N\\\sum F_x = -2.01N[/tex]
The sum of force along the vertical is expressed as:
[tex]\sum F_y = +10N[/tex]
Calculate the magnitude of the force:
[tex]F=\sqrt{(\sum F_x)^2+(\sum F_y)^2} \\F=\sqrt{(-2.01)^2+(10)^2} \\F=\sqrt{104.0401}\\F= 10.2N[/tex]
Hence the magnitude of the resultant force is 10.2N
Find the direction
[tex]\theta = tan^{-1}\frac{y}{x}\\ \theta = tan^{-1}\frac{10}{-2.01}\\\theta =tan^{-1}(-4.9751)\\\theta =-78.63^0\\\theta = 180-78.63 = 101.36^0[/tex]
Hence the magnitude and direction of the resultant force are 10.0N and 101.36⁰

why are hydraulic brakes less effective if there is air in the liquid
Answer:
air is compress able
since air can be compressed, then the hydraulics will not work as well. It won't be able to push the object or brake the wheels. Since water cannot be compressed, it is able to push something, that's how hydraulics work.
Explanation:
it reduces pressure and essentially makes the process less effective.
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

What is exercise?Exercise is any activity that utilizes the physical movements of the body that improves a people's health, endurance, and wellbeing while lowering their chance of contracting illnesses. It enables the person to keep their body weight in a healthy weight range.
The benefits of fitness fluctuate depending on the sort of dying a person experiences. Even if a muscle is stretched, excessive sitting can cause a number of illnesses, many of which are fatal. The individual should engage in mobility activities as well as exercising to improve their stamina.
Thus, exercise is very necessary for health.

A boy exerts an unknown horizontal force as he pulls a 52 N sled across packed snow. The coefficient of friction is 0.12. If a person weighing 650 N sits on the sled, what force is needed to pull the sled across the snow at constant speed?
Answer:
0.62
Explanation:
Ff = mg = 52 N
Since the speed is constant, the friction
force equals the force exerted by the
girl, 36 N.
Ff = ukFn
so uK = Ff/Fn
= 36 N/52 N
= 0.69
Force is needed to pull the sled across the snow at constant speed is 0.62 N
What is force?A force in physics is an effect that has the power to alter an object's motion. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Given in the question a boy exerts an unknown horizontal force as he pulls a 52 N sled across packed snow. The coefficient of friction is 0.12. If a person weighing 650 N sits on the sled,
Ff = mg = 52 N
Since the speed is constant, the friction force equals the force exerted by the boy, 36 N.
Ff = (uk).(Fn)
so uK = Ff/Fn
= 36 N/52 N
= 0.69 N
Force is needed to pull the sled across the snow at constant speed is 0.62 N

A ball Of Mass. 0.5 kg initially at rest is kick directly toward offense from appoint 20 m away as shown below the velocity of the ball as it leaves the kickers foot is 16 M/S at angle 45 degrees above the horizontal the top of the fence is 4 m high the ball hits nothing Wallen flight and a resistance is negligible the acceleration due to gravity is 9.8 M/S^2 determine the time it takes for the ball to reach the plane of the fence.
Answer:
a. The horizontal component of the velocity is constant so vxt = d where vx = v0 cosθ = 16m/s t = d/v = 2s
b. The height of the ball during its flight is given by y = v0yt + ½ gt2 where v0y = v0sinθ = 12m/s and g = –9.8m/s2 which gives at t = 2s, y = 4.4m. The fence is 2.5m high so the ball passes above the fence by 4.4m – 2.5m = 1.9m

explain why so much thermal energy is released in a chain reaction
Answer:
It is the chain reaction process that is used in reactors and nuclear weapons to generate a large number of fissions. In a reactor, the propagation of fissions takes place in a controlled manner, in a nuclear weapon in an uncontrolled, explosive manner.
The products of nuclear fission are usually accompanied by two to three secondary, free neutrons which can be absorbed later by other fissile nuclei. These absorptions in turn lead to further fissions, then to the production of other neutrons etc ..., a process commonly called chain reaction.
A cheetah running initially at a velocity of 20 m/s accelerates
uniformly at 3.0 m/s. The velocity of the cheetah will be
m/s after 4.0 seconds.
Answer: I think it’s 32 m/s
Explanation: Vi=20 m/s
Vf=?
a=3.0 m/s^2
t= 4s
Vf= Vi + at
Vf= 20 m/s + (3 m/s^2)(4s)
Vf= 20 m/s + 12m/s
Vf= 32m/s
If A cheetah running initially at a velocity of 20 m/s accelerates
uniformly at 3.0 m/s2. The velocity of the cheetah after 4.0 seconds will be 32 m/s.
To find the velocity of the cheetah after some time we can use the formula:
v = u + at
where:
v = final velocity
u = initial velocity
a = acceleration
t = time
Given:
Initial velocity (u) = 20 m/s
Acceleration (a) = 3.0 m/s²
Time (t) = 4.0 seconds
now we can put values in eq.
v = 20 m/s + (3.0 m/s²) * 4.0 s
v = 20 m/s + 12 m/s
v = 32 m/s
so the answer is 32 m/s.
