Answer:
The mechanical advantage is 1.
Explanation:
Given;
input force, F₁ = 10 N
output force, F₀ = 10 N
mechanical advantage is called force ratio and it is given as;
M.A = output force / input force
M.A = 10 N / 10 N
M.A = 1
This is an ideal machine scenario.
Therefore, the mechanical advantage is 1.
Answer:
Explanation:
mass of charged particle m = 6 x 10⁻³ kg .
speed of particle v = 4 x 10³ m /s
speed of particle perpendicular to magnetic field = v sin37
= 4 x 10³ sin37
= 2.41 x 10³ m / s
Force on charged particle
= B q v , B is magnetic field , q is charge on particle and v is velocity perpendicular to B
Force = ma
= 6 x 10⁻³ x 8
= 48 x 10⁻³
Force = Bqv
48 x 10⁻³ = 5 x 10⁻³ q x 2.41 x 10³
q = 48 x 10⁻³ / (5 x 2.41)
= 3.98 x 10⁻³C.
your answer will be D Strong nuclear force is most like electric because they are both related to distance.
Answer: Temperature inversion
Explanation: Temperature inversion is a reverse of the normal temperature flow or distribution of the air,it usually causes temperature to rise as altitude increase towards the troposphere instead of reduction of temperature.
Temperature inversion is caused when warm,dense air flow above cold,less dense air. Temperature inversion is hazardous to man as it traps pollutants close to the Earth surface,this condition limits vertical circulation.
