Answer:
30m/s^2
Explanation:
Acceleration=Final Velocity-Initial Velocity/Time
10m/s^2= Final Velocity-0m/s/3
30m/s^2= Final Velocity
Final Velocity=30m/s^2
Answer:
a. collectivism
Explanation:
the practice or principle of giving a group priority over each individual in it.
A good example of this is culture. Collectivism in cultural terms refers to a culture that privileges family and community over individuals. For example, children in collectivist societies are likely to take care of elderly parents if they fall ill and will change their own plans in the event of a family emergency.
Answer:
2.27kg
Explanation:
The Potential energy gained = Force gravity× Height
Force gravity on the ball is GPE/ height
56.8/2.5=22.72N
the mass = 22.72/10= 2.27kg
Answer:
Constructive Interference.
Explanation:
Constructive Interference.
Definition:
Two waves meet in such a way their highs(Crests) combine to form a new waves whose magnitude is the sum of magnitude of combining waves.
Since two waves have same wavelength and are in phase so when they combine they well form a way which has the magnitude equal to the sum of the magnitude of both waves.
Reasons why it is Constructive Interference:Waves
- Have Same wavelength
- Are in phase (Can have phase difference of 2π
- Have crests aligned with each other (Appear at same point)
Answer:
The diameter of the moon's image is 0.31 cm.
Explanation:
Given that,
Focal length = 34.3 cm
Diameter of the moon 
Mean distance from the earth 
At that distance the object is assumes to be at infinity. hence the image will be formed at a distance equal to focal length
So, the image distance is 34.3 cm.
We need to calculate the diameter of the moon's image
Using formula of magnification
Hence, The diameter of the moon's image is 0.31 cm.
