Answer:
as the mass of an object is increased, the acceleration of the object is decreased & vice-versa.
Explanation:
hope this helps!
Answer:
Part a)
a = - 8.45 m/s/s
Part b)
Part c)
Explanation:
Part a)
when car apply brakes then the friction force on the car in front of us is given as
here we need to find deceleration due to friction
Part b)
Braking distance of the car is the distance that it move till it stops
so we will have
Part c)
Since we know that average reaction time for human is 0.424 s
now we know that during reaction time our car will travel at uniform speed
so we will have
Answer:
Doubled
Explanation:
F = (kq1q2) / r^2
F and q (Either q1 or q2) are directly proportional, so double the charge would also double the electruc force between the charges.
Answer:
The charge is
Explanation:
Given that,
Distance = 2.5 mm
Electric field = 800 NC
Length
We need to calculate the linear charge density
Using formula of linear charge density
Put the value into the formula
We need to calculate the charge
Using formula of charge
Put the value into the formula
Hence, The charge is
Density formula: d = M/V
So I think the answer would be 5.67/ 835 I am not sure of the answer I got confused (´∀`) but I hope it will help
