<span>The answer is contracted or repeatedly contracted. Resistance exercises are a set of exercises that forces the skeletal muscles of an individual's body to contract. Resistance exercises are used to enlarge muscular mass of an individual's body or to increase strength and endurance of a person.</span><span />
It's is True that your body temperature your body converts chemical potential energy into thermal energy
A famous person that makes me happy would Siennamae; her platform is based on body positivity and encouraging people to be more confident about who they are. A mobile app that makes me happy would be uber eats, this is because it allows me to order food at any given time of the day and i love food. An opportunity that makes me smile would be the opportunity to help the homeless and the orphans in the future because of how messed the system is, thinking about helping people brings joy to my heart.
Answer:
voltage measured by the voltmeter = (E × RV)/(r + RV)
Explanation:
The circuit diagram for this description is presented in the attached image.
The internal resistance of an emf source is modelled to be in series with the source.
Therefore, the end product is a circuit with the battery in series connection with the internal resistance and resistance of the volunteer. The voltage picked up by the volunteer is the voltage across resistor RV.
Total resistance in the circuit = (r + RV) ohms (since both resistors are in parallel)
Current produced by the emf source = E/(Total resistance) = E/(r + RV)
The voltage across resistor RV = current flowing through this resistor × its resistance.
Since all the circuit elements are in series with each other, same current, E/(r + RV) flows through them all
Voltage across RV = voltage measured by the voltmeter = [E/(r + RV)] × RV = (E × RV)/(r + RV) = (E.RV)/(r + RV)
Answer:
G = 6.6675 x N/
Explanation:
From Newton's law of universal gravitation,
F = .................. 1
Where F is the force of attraction, G is the universal gravitation constant, M is the mass of a massive object e.g earth, m is the mass of the smaller object e.g moon, r is the radius of the massive object.
Newton's second law states;
F = mg ................... 2
F is the force, m is the mass of the object and g is the gravitational force on the object.
Equating equations 1 and 2 gives;
mg =
So that;
g =
⇒ G =
where: g = 9.81 m/, r = 6371 km, M = 5.972 x kg.
G =
=
= 6.6675 x N/
The Universal Gravitational Constant (G) is 6.6675 x N/.
