What is the name of the process where an object is exposed to nuclear radiation

Answer:

it may be because of the movement of the atoms. i believe that the heat of the warm water makes it move faster, thus making the object float due to upthrust, or air pressure

In the given baseball the blue line represents gravity. Gravitational Force attracts the objects towards the center of the earth.

It is the force that attracts the objects towards the center of the earth. Every massive object has gravitational force but it is negligible for smaller objects.

Friction force works against the direction of the motion of the objects.  The Normal force is the reaction of the gravitational force hence it acts upwards.

Therefore, in the given baseball the blue line represents gravity.

The force exerted by the string on the object will be 2.7 Newton.

The formula to calculate the centripetal force is as follows -

F[C] = mv²/r

Given is an object of mass 0.9 kg is attached to a massless string of length 3 m, and swung with a tangential velocity of 3 m/s.

The force exerted by the string on the object will be equal to the centripetal force acting on the object. In order to make a body perform circular motion about any center point, a centripetal force is needed, which is directed towards the center of the circle formed due to the circular motion. Therefore -

F[C] = mv²/r

F[C] = 0.9 x 3 x 3 / 3

F[C] = 2.7 Newton

Therefore, the force exerted by the string on the object will be 2.7 Newton.

                       =1/2 x 10 x (12)^2

                       =720J

Explanation:

Answer:

Agree

Explanation:

Distance is described as "how much ground an object is covered" in physics, and because the object is moving, no matter which direction, it is constantly gaining more distance. You can think of the object as a car, and as the car is moving down a highway it is gaining more and more distance as the seconds go by.

You might be confused with the term displacement, "how far out of place an object is" which in this case would be false.

Does that make sense?

Answer:

  17 1/7 cm ≈ 17.1 cm in front of the mirror

Explanation:

You want the location of the image formed of an object placed 40.0 cm in front of a concave mirror with radius of curvature 24.0 cm. The object is 2.5 cm tall.

For a spherical concave mirror with radius of curvature r, the relationship between the distance from the mirror to the image (i) and the distance from the mirror to the object (o) is ...

  2/r = 1/i +1/o

Solving for i, we get ...

  i = 1/(2/r -1/o) = 1/(2/24 -1/40) = 120/7 = 17 1/7 ≈ 17.1 . . . . cm

The image will be formed about 17.1 cm in front of the mirror.

__

Additional comment

The magnification is -i/o = (-120/7)/40 = -3/7. The image height is about -15/14 ≈ -1.07 cm. The minus sign means the image is inverted with respect to the object.

The actual formula uses 1/f where f is the focal length. The "small angle approximation" for a spherical mirror says f = r/2, so 1/f = 2/r.

The attachment shows calculation of the image height as well as its location.

If an object moves, stops, changes speed, or even changes direction, then that condition represents the unbalanced force condition.

The unbalanced force is the magnitude of the net force that tends to cause the motion of objects.

It is nothing but the greater amount of force to be applied to the object to displace the object in either direction.

If an object is moving, stopping, changing the speed, or changing the direction, then such activities directly show that the object is changing its state of motion.

And the change in the motion is only caused when there is some magnitude of force associated with it.

When the magnitude of forces applied on an object such that one force is greater than another in a specific direction, then such forces are known as unbalanced forces.

Unbalanced forces cause motion, which means a body can move, stop or even can change its direction due to the unbalanced force.

Thus, we can conclude that if an object moves, stops, changes speed, or even changes direction, then that condition represents the unbalanced force condition.

Hey there ;),

Given:

Density of mercury=13600 kgm^-3

Lets find the atmospheric pressure at sea level in Pascal.

To find atm pressure, apply formula-

Pressure = h×p×g

where height = 0.76 m, p as 13600 kgm^-3 and acceleration due to gravity as 9.8 m/s²

Finding Atm,

Pressure = 0.76×13600×9.8

→ Pressure = 101292.8

→ Pressure = 101293

Therefore, atmospheric pressure is 101293 Pa

From the question we are told

In the same year, the average finishing time for U.S. women was 4 hours and 41 minutes. What was the average female speed in miles per hour?

This is defined as the collective mean of different travel intervals

Generally the equation for Speed   is mathematically given as

V=\frac{Distance}{Time}

Therefore

For  4 hours and 41 minutes=4.683hours

This travels time was obtained over a  series of distance

Commensalism is a type of ecological interaction in which one organism benefits (in this case, the tree)  and the other organism neither benefits nor harm (the megabat).

Mutualism is a type of ecological association in which both organisms benefit from such interaction.

Conversely, parasitism is a type of ecological interaction in which one organism benefits and the other organism is harmed.

Answer:

C

Explanation:

Pascals are the units for measuring pressure

Known :

S = 205 m

t = 0.6 s

Solution :

Sound speed

v = S/t

v = (205 m)/(0.6 s)

v = 341.67 m/s

Air Temperature

v² = γRT

(341.67 m/s)² = (1.4)(286 m²/s²·K)(T)

T = 291.5 K
