7. A some s dropped from the top of a tower 500 m high into a pond of water at
the base of the tower. When is the splash heard at the top ?
= 10 ms and speed of sound = 340 ms?)​

Answers

Answer 1

Answer:

11.47answer

Explanation:

Height of the tower, s = 500 m

Velocity of sound, v = 340 m sˆ’1

Acceleration due to gravity, g = 10 m sˆ’2

Initial velocity of the stone, u = 0 (since the stone is initially at rest)

Time taken by the stone to fall to the base of the tower, t1

According to the second equation of motion:

S = ut1 + 1/2gt12

500 = 0 x t1 + 1/2 x 10 x t12

t12 = 100

t1 = 10s

Now, time taken by the sound to reach the top from the base of the tower, t2= 500/340 = 1.47 s

Therefore, the splash is heard at the top after time, t

Where, t= t1 + t2 = 10 + 1.47 = 11.47 s.

What can you do to look out for the safety of others?

Answers

You can check up on others and ask what they’re doing. Keep an eye out for suspicious activity and if you feel like someone is in danger, intervene by making responsible choices, depending on how severe the situation is. The benefit of looking out for others safety is also making sure of your own so always be aware of your surroundings.

Answer:

Nothing

The research finding indicating that goal achievement generally leads to expressions of joy across cultures provides support for the claim that _________.

Answers

Answer:

events triggering specific emotions are generally consistent across cultures.

Explanation:

Culture can be defined as the general way of life of a group of people living together in a particular location or society.

Basically, culture comprises of beliefs, values, behaviors, language, dressing, cuisine, music, symbols, arts, social habits, knowledge, customs, laws pertaining to a particular group of people living together in a society.

This ultimately implies that, culture are acquired and passed from one generation to another.

A cultural trait can be defined as the smallest characteristics of human activity (actions) that is mainly acquired socially and transmitted from one generation to another through various modes of communication. Thus, these unique behavioral informations or characteristics and beliefs acquired by people socially are transmitted from one individual or group of people to another.

Basically, cultural traits play a significant role in the way of life of a group of people in that it is a unique collection of various cultural elements that are closely related such as behaviors and beliefs.

Hence, any research finding indicating that goal achievement generally leads to expressions of joy across cultures provides support for the claim that events triggering specific emotions are generally consistent across cultures.

For example, when Vice President Kamala Harris was elected as the Vice President of the United States of America, the Black Americans and Indians were so joyous about the event.
