Answer:
Explanation:
Given that :
The current I = 8.6 A
The length vector L = 2.3 m i
The force vector is = -2.0 j N
When L = 2.3 m i ; the
Force vector F = (2.0 i - 4.8 k) N
Compute the components of the magnetic field as follows:
Replacing 8.6 A for I ; -2.0 j N for F & 2.3 m i for L
However in y direction ; we have :
Hence, the component of magnetic field is as follows:
First calculate the time by using following equation:<span>
d= (vi+vf)/2 x t </span>
where t = time
vi is the initial velocity = 23 m/s
<span>vf is the final velocity = 0 m/s</span>
and d is the distance covered = 85m
85 = (23 + 0)/2 x t
t = 85/11.5 = 7.39s
Now use this equation to find acceleration:
a= (vf-vi)/t <span>
a = 0 – 23/ 7.39</span>
a = -3.112 m/s²
<span>so, the acceleration is 3.112 m/s</span>²<span>

Answer:
F = 75.49 N
Explanation:
given,
atmospheric pressure Po = 1 atm
Po = 101325 Pa
diameter =3.08 cm,
radius = 1.54 cm
1 cm = 0.01 m
1.54 cm = 0.0154 m
Force = Pressure x area
area = π r²
Force = 101325 Pa x π x 0.0154 x 0.0154
F = 75.49 N
Weight of the heaviest brick that the cleaner can lift is F = 75.49 N
Because it cant expand it can only change its shape
