A car rolls down a ramp in a parking garage. The horizontal position of the car in meters over time is shown below. Graph of horizontal position x (in meters) on y axis and time (in seconds) on x axis. The initial position is -3 m at t=0 s, and the position increases linearly to 3 m at t=8 s. Then the position is constant at 3 m until t=16 s, then increases linearly to 9 m at t=24 s.

Answer:9.82 m

Explanation:

As we know from equation of motion

S=v*t +0.5 a t^2

Know s=H/2

a =9.82

t=1

V=0

Plugging the values

H*0.5=0+0.5*9.82*1^2

H=9.82 m

Answer: give up because nothing can be done.

Explanation:

You would have to give up because you have taken on an impossible task. And nothing can be done because there is no known means available to you to measure or observe what is happening outside the spaceship. And as a result this has made it an impossible task knowing the velocity of the ship or finding out.

Answer:

South and West

Those people are pushing the hardest. It will move south faster than it moves west.

Explanation:

Explanation:

The velocity of the wave is:

v = (9.0π rad/s) / (0.1π / cm)

v = 90 cm/s

v = 0.9 m/s

Velocity of a standing wave on a stretched string is:

v = √(T / (m/L))

0.9 m/s = √(0.081 N / (M / 2.0 m))

0.81 m²/s² = 0.081 N / (M / 2.0 m)

M / 2.0 m = 0.1 kg/m

M = 0.2 kg

Explanation:

Radiation is often categorized as either ionizing or non-ionizing depending on the energy of the radiated particles. Ionizing radiation carries more than 10 eV, which is enough to ionize atoms and molecules and break chemical bonds. This is an important distinction due to the large difference in harmfulness to living organisms. A common source of ionizing radiation is radioactive materials that emit α, β, or γ radiation, consisting of helium nuclei, electrons or positrons, and photons, respectively. Other sources include X-rays from medical radiography examinations and muons, mesons, positrons, neutrons and other particles that constitute the secondary cosmic rays that are produced after primary cosmic rays interact with Earth's atmosphere.

Answer:

47.515 cm²

In meter square= 4.7515 *10^-3 m²

Explanation:

The radius of a circle = 5.5 cm

In meter= 5.5*0.01

= 0.055 m

the circumference= 34.56 cm

in meters = 34.56 cm*0.01

= 0.3456 meters

the area= 95.03 cm²

in square meters =95.03*(0.01)²

in square meters= 9.503*10^-3 m²

. area under the curve at the right

= Area of semi circle

= Area of circle/2

= 95.03 /2

= 47.515 cm²

In meter square= 4.7515 *10^-3 m²

Answer:

A lithium atom has 3 protons and 3 electrons. It can lose one of its electrons, making it an ion. It now has more positive protons than electrons so it has an overall positive charge. Therefore it is a positive ion.

Explanation:

It is given that, the volume of air is 53.28 m³. We need to convert it into scientific notation.

Any number in scientific notation can be given by :

[tex]N=a\times 10^b[/tex]

a is real no and b is any integer

We have, V = 53.28 m³

To write it into scientific notation, shift decimal before 3 such that,

[tex]V=\dfrac{5328}{100}[/tex]

No multiply and divide by 10. So,

[tex]V=\dfrac{5328}{100}\times \dfrac{10}{10}\\\\V=\dfrac{5328}{1000}\times 10\\\\V=5.328\times 10^1\ m^3[/tex]

So, the correct option is (a).

Answer:

Kinetic energy=1/2 mv^2.

which is 1,000,000,000=1/2×90,000×v^2.

1000000000=45,000v^2.

v^2=222.22.

v=√222.22.

v=14.9~15m/s.

The speed of a 90,000 kg airplane with a kinetic energy of one billion Joules would be 149.07 m/s

Mechanical energy is the combination of all the energy in motion represented by total kinetic energy and the total potential energy stored energy in the system which is represented by total potential energy.

Total mechanical energy is s the sum of all the kinetic as well as potential energy stored in the system.

ME = KE + PE

As given in the problem we have to calculate the speed of an airplane with a mass of 90,000 kg and kinetic energy of one billion Joules.

m= 90000 kg

K.E = 1 billion Joules

     = 1,000,000,000 Joules

The total kinetic energy

KE = 1/2mv²

By substituting the respective values in the formula of kinetic energy

1,000,000,000 J = 1/2×90000 ×v²

v² = 1,000,000,000 ×2/90000

v² = 22222.222

v =149.07 m/s

Thus, the speed of a 90,000 kg airplane with a kinetic energy of one billion Joules would be 149.07 m/s

our answer would be 4m/s^2

Answer:

Both technicians are correct

Explanation:

In electromagnetic induction, the induced voltage can be increased by increasing the relative speed between the conductor and the magnetic line of force, by increasing the strength of the magnetic field, which increases the magnetic lines of force, Increase the strength of the magnetic field, so there are more flux lines, and also by increasing the angle between the flux lines and the conductor to a maximum of 90 degrees.

When the bat strikes the ball, the ball pushes against the bat due to reaction force, The correct option is D.

It is a type of force that acts in the opposite direction of the applied force, for example when one applies active force towards the stationery wall, the wall exerts a reactive force in the opposite direction.

Therefore when a girl hits a baseball with a bat, the baseball applies an active force on the ball in which as a result of reactive force the ball pushes against the bat.

Answer:

The length of days and nights change with the seasons.

Explanation:

Distance from the equator along with the tilt of Earth's rotational axis contributes to day and night period differences. Daylight hours or the period of sunlight exposure vary due to the inclined axis of the latitudes. In the northern hemisphere during summers, the tilt of the axis is towards the sun which brought more sunlight to the exposed region. And therefore the length of day hours is more than the southern hemisphere which at the same time will be tilted away from the sun.
