Answer:
Explanation:
given,
radius of earth = 6378 km
distance separating the center of the earth and moon = 384400 km
we know acceleration due to gravity
hence, the weight of earth compared to the your weight on earths surface is equal to 2 × 10⁻⁴ g.
Answer:
4.16m/s²
Explanation:
According to Newtons second law;
Fm is the moving force
is the coefficient of kinetic friction between the child and the slide
m is the mass
g is the acceleration due to gravity
a is the acceleration of the child
Substitute the given values and get the acceleration as shown;
35(9.8)sin27.5 - 0.415(35)(cos27.5) = 35a
158.38-12.88 = 35a
145.49 = 35a
a = 145.49/35
a = 4.16m/s²
Hence the acceleration of the body is 4.16m/s²
A resistor in a circuit acts as a switch to control the flow of charge in a circuit.
<u>Explanation:</u>
An electrical components that plays a role of limiting or regulating the electrical current flow is termed as Resistor. It can be helpful for the purpose of giving certain voltage to a device like a transistor. The current that is passing through a resistor has a inverse proportionality with its resistance and direct proportionality to the voltage that is passing across it., provided another factors remaining unchanged. This can be explained by Ohm's Law.
The electric current that is passing through an electrical circuit will always be dependent on the the voltage and the resistance. When the current flowing throgh a circuit is larger then it can result in heating that damages and burn he resistors or the objects that is present around the circuit.
If earth<span> were to every pull back on that object, this is where its kinetic energy will come from. Regarding some other planet pulling it, note that there is currently potential energy stored in the object(when it is on</span>earth<span>), in the other planet's gravitational field.</span>
