Answer:
<em><u>A balance and a beaker of water!</u></em>
Explanation:
Krishne wants to measure the mass and volume of a key. The tools that are to be used are – a balance and a beaker of water.
Mass will be represent with the amount of matter that is in an object. This will be measured in terms of kilogram. The mass can easily be measured with balance.
Volume is the quantity of matter that is in the object. This is measured in terms of cubic meter. If you drop the key in a beaker of water, the water inside the beaker will increase and this increases the volume of water that will be equal to volume of key.
<span>When the question says the ball lands a distance of 235 meters from the release point, we can assume this means the horizontal distance is 235 meters.
Let's calculate the time for the ball to fall 235 meters to the ground.
y = (1/2)gt^2
t^2 = 2y / g
t = sqrt{ 2y / g }
t = sqrt{ (2) (235 m) / (9.81 m/s^2) }
t = 6.9217 s
We can use the time t to find the horizontal speed.
v = d / t
v = 235 m / 6.9217 s
v = 33.95 m/s
Since the horizontal speed is the speed of the plane, the speed of the plane is 33.95 m/s</span>
Answer:
there are 5 main aspects of personal health: physical, emotional,social,spiritual, and intellectual.
physical weelness indicates a high levelnof endurance, flexibility and strength. it incorporates daily exercise through cardiovascular and muscular activities.
mental or emotional wellness focuses on an acceptance and afreement with one's emotions and feelings. A person need to reach a high level of self-respect and dignoty.
lifestyle wellness doesn't have a definite, agreed upon route or direction for accomplishment. lifestyle wellness incoporates many different dimentions of wellness. but deals mostly with having a balanced lifestyle. every person has a different idea of what a balanced idea includes.
intellectual wellness encourages us to engage in creative and mentallu-stimulating activities. these activities should expand ur knowledge and skills while allowing you to share ur knowledge and skills with others. intellectual knowledge includes learning. its important to explore new ideas and understanding in order to become more mindful and better-rounded. having an optimal level of intellectual wellness inspires exploration. also stimulates curiosity.
While plane is moving under tailwind condition it took time "t"
so here we will have
here net speed of the plane will be given as
similarly when it moves under the condition of headwind its net speed is given as
now time taken to cover the distance is 2 hours more
now solving two equations
solving above for v_w we got
