We can use the equation of motion:
× 
Since the acceleration and velocity are both downward, we will regard the downhill direction as positive.
Solving the quadratic:
Negative time is not possible so the second value is discarded. Time taken 
seconds
<h3>
What is a time interval in physics?</h3>
A larger span of time can be broken up into several shorter, equal-length segments. These are referred to as time periods. Consider the scenario where you wished to gauge a car's speed over an hour-long trip. You could break up an hour into ten-minute segments. A time interval is the length of time between two specific points in time.
For example, "The time difference between 3:00 and 4:00 is 1 hour."

Explanation:
The of formic acid is pK 3.750. what is the Ka of formic acid?
Answer:
Explanation:
given,
Speed of sound = 343 m/s
frequency of horn = 260 Hz
the friend is approaching, the frequency is increased by the Doppler Effect. The frequency is 266 Hz
using formula
the speed of friends approaching is equal to
That states that the blackhole ends are working like bridges between one space to another.
- And you can travel through them in 5-10s
- The distance is thousands of lightyears but we can travel it..
This may be possible
Answer:
Electric field will remain same.
Explanation:
Given that
At initial condition ,charge q = +3μ C
Electric field E = 4106 N/c
As we know that
Electric field due to charge q
Now when charge is replaced by new charge q'= -3μ C
From the expression of electric field we can say that electric field will remain same from same quantity of electric charge.
So we can say that electric field will remain same.
