Answer:
(a). The magnitude of the acceleration of the proton is
(b). The initial peed of the protion is
(c). The time is .
Explanation:
Given that,
Electric field
Time = 5.0 sec
Distance 7.00 cm
(a). We need to calculate the acceleration
Using formula of force
Where, E = electric field
m = mass of proton
q = charge of proton
Put the value into the formula
The magnitude of the acceleration of the proton is
(b). We need to calculate the initial peed
Using equation of motion
Where, s = distance
Put the value into the formula
The initial peed of the protion is
(c). We need to calculate the time interval over which the proton comes to rest
Using formula
Where, u = initial velocity
a = acceleration
Put the value into the formula
Hence, (a). The magnitude of the acceleration of the proton is
(b). The initial peed of the protion is
(c). The time is .
Object true weight is given as
now we know that g = 9.8 m/s^2
now when it is complete submerged in water its apparent weight is given as 82 N
apparent weight = weight - buoyancy force
apparent weight = 82 N
weight = 123 N
now we have
82 = 123 - buoyancy force
buoyancy force = 123 - 82 = 41 N
now we also know that buoyancy force is given as
now as we know that mass of the object is 12.55 kg
its volume is 4.18 * 10^-3 m^3
now we know that density will be given as mass per unit volume
so here density of object is 3002.4 kg/m^3
