Answer:
C) 40,000 Joules
Explanation:
½(1000)10² - 10000 = 40000
Humans need a digestive system to do cellular respiration, which produces energy used for growth and movement.
Plants do not need one as they make their own energy through photosynthesis. The process produces glucose, which is a form of energy for the plants.
Answer: EL ZINC ES EL ELEMENTO PURO PORQUE NO HA REACCIONADO CON NINGÚN OTRO METAL O NO METAL. EL SULFURO DE ZINC ES UN COMPUESTO PORQUE HA REACCIONADO CON EL AZUFRE PARA HACER EL COMPUESTO.
english:
ZINC IS THE PURE ELEMENT BECAUSE IT HAS NOT REACTED WITH ANY OF OTHER METAL OR NONMETAL. ZINC SULPHIDE IS A COMPOUND BECAUSE IT HAS REACTED WITH SULPHUR TO MAKE COMPOUND.
Answer:
Explanation:
The forces acting on a conductor carrying current placed in a magnetic field is analysed using the Fleming's left hand rule.
The rule states that "If the fire finger, the middle finger and the thumb are held mutually perpendicular to one another in a magnetic field, the fore finger acts in the direction of the magnetic field, the middle finger acts on the direction of the current while the thumb acts in the direction of the force.
Based on the rule, it can be inferred this current carrying wire placed in the magnetic field acts perpendicular to the magnetic field and force acting on the wire.
Answer:
Current through the surface at t = 1.1 s is 21.37 A.
Explanation:
The charge is passing through a surface of area varies with time as :
Here,
t is in seconds
The rate of change of electric charge is called electric current. It is given by :
At t = 1.1 s, Current,
So, the instantaneous current through the surface at t = 1.1 s is 21.37 A.
