According to Newton's second law of motion, acceleration of an object depends upon the mass of the object and the force acting on it
Explanation:
- The equation for the second law is F = Ma, where m is the mass of the object, a is the acceleration and F is the force acting on it
- Newton's second law of motion is applied in many situations for example, if you apply the same amount of force to pull a car and a truck. We all know that the car will move and the truck will not because the car has less mass than the truck. So, the truck needs more force to apply for it to move.
The answer should be B.

The higher the frequency, the higher or sharper (the musical term if you prefer such things) the pitch is.
Answer:
-4.4 m/s
Explanation:
Since the ball is thrown upward, we can ignore the horizontal velocity. This means that the vertical velocity is 25 m/s. The vertical acceleration is -9.8 m/s^2 (g). This means that after 3 seconds, the velocity would've decreased by 9.8 m/s^2 * 3 s. This is 29.4 m/s.
This should be subtracted from the initial velocity:
25 m/s - 29.4 m/s = -4.4 m/s
Hope this helps!
We need to directly measure the spectral type in order to determine the surface temperature of a star.
<h3>How do you find the properties of a star?</h3>
Astronomers can determine the temperature of a star by looking at its color and spectrum. The apparent brightness of a star describes how luminous it looks to us. The brightness of a star tells us how bright it really is. The luminance can be determined using both the perceived brightness and the distance.
A star's luminosity, or the total amount of energy it emits each second, is determined by two factors: The stellar photosphere's "Effective Temperature," T. the star's total surface area, which is influenced by its radius, R.
Because it controls how much fuel a star has and how quickly it burns it, a star's mass is its most fundamental characteristic. The majority of a star's life is spent burning hydrogen into helium in its core, which generates energy. The star needs to achieve a balance between gravity and outward pressure in order to continue to be "alive."
