for acceleration we can define that rate of change in velocity is know as acceleration
So whenever velocity of train is changing with time we can say train is accelerating
Now here if initially train is standstill then after some time its speed is 5 m/s
so here the train is accelerated first time
Then on straight path its speed changed from 5 m/s to 10 m/s so here train gets accelerated second time
After this train chugged around a curve with same speed 10 m/s
SO here since train is moving in curve so here its direction of velocity is continuously changing and this type of acceleration is known as centripetal acceleration
SO this is accelerated Third time
Then its speed decreases and it comes to speed of 5 m/s from 10 m/s
So here it is acceleration of train for Fourth time
Then finally train comes to stop so again its speed changed from 5 m/s to 0
so this is acceleration of train Fifth time
So total train will accelerate 5 times in whole path
Answer:
weave lanes
Explanation:
Road engineers have to be especially creative when they must design an infrastructure that allows several major roads to cross, with the aim of improving traffic flow making optimal use of space.
The partial cloverleaf: With a very popular design usually widely used in places where interstate highways meet state and / or local roads. Usually you include interlaced lines (or weaves lanes) that allow adequate traffic circulation both to enter and exit to the main road.
Answer:
gravitational force electric force and magnetic force
Tasting or touching solutions to identify whether it is an acid or a base is something that you should always avoid since it can be dangerous and, in some cases, deadly.
<span>Phenolphthalein is typically used to test the pH level of a solution. Since you can determine whether a solution is an acid or a base by identifying the pH level, this is one of the correct answers.
</span>However, the question says to "select all that apply," so let's also check the last option, litmus paper.
Litmus paper is commonly used to identify whether something is an acid or a base. When blue litmus paper is exposed to an acid, it turns red. When red litmus paper is exposed to bases, it turns blue.
This means that the answers you should select are both litmus paper and <span>phenolphthalein.
Hope this helps!</span>
Answer:
Explanation:
Given data;
Two hanging mass is given as m1 and m2
Mass of pulley is given as m3
radius of pulley is r
Assuming mass m1 is greater than m2
Take downward direction for mass m1
and upward direction for mass m2
and clockwise direction of pulley is positive
from newton second law on each mass
for Mass m1
for Mass m2
fro pulley
