Answer:
Power required will be 7.2 watt
Explanation:
We have given battery of Barble jeep is 6 volt
So potential difference V = 6 volt
Resistance of electric motor R = 5 ohm '
We have to find the power motor using to drive the jeep
Power is given by 
, here V is voltage and R is resistance
So 
Answer:
A.Gravity acts to pull the object down
D.The object’s inertia carries it forward.
E.The path of the object is curved.
Explanation:
The motion of a projectile consists of two independent motions:
- A uniform motion along the horizontal direction, with constant horizontal speed
- A vertical motion with constant acceleration of g = 9.8 m/s^2 downward (acceleration due to gravity), due to the presence of the force of gravity, so the vertical velocity changes (increases in the downward direction)
As a result, the combined motion of the projectile has a curved trajectory (parabolic, more specifically). So the following options are correct:
A.Gravity acts to pull the object down --> gravity acts along the vertical direction
D.The object’s inertia carries it forward. --> there are no forces acting along the horizontal direction (if we neglect air resistance), so the horizontal motion continues with constant speed
E.The path of the object is curved
Answer:
Cape Point lighthouse
Explanation:
The lighthouse is located South of Cape Town, at a point where boats turn to go around the tip of Africa.
The new lighthouse has the most powerful light of all the lighthouses in South Africa, with a power of 10 megacandelas. That's why it's being visible for up to 63 km around.
It's a very important lighthouse helping to conduct the traffic around dangerous waters where 2 oceans meet.
Answer:
Datos:
q1 = -50 μC = 
q2 = +30 μC = 
F = 10 N
a) x si la <em>F = 10N</em>
Aplicando la Ley de Coulomb:
x = 
= 
= 1,162m
b) x si la <em>F = 20 N</em>
x=<em> </em>
<em> </em>= 0,822m
c)x si la <em>F = 50 N</em>
x = 
= 0,520m
