Vf =Vi + at
Vi =Vf - at
= 34 - 15•13
= - 161 m/s :/
Answer:
DMM should be placed in the series combination with the circuit.
Explanation:
DMM is the digital multi meter. It can measure the voltage, current and resistance at a time.
- While measuring the current with the DMM you must be ensure that the DMM should be connected with the circuit in series combination. So that it will give the resultant current accurately.
- While measuring the voltage the observer should check the open probes.

Answer:
Iron
Explanation:
H = mc∅
Above equation can be used here to find the answer to the question. this equation gives us the relationship between the heat energy supplied to a material and the temperature difference that the material would go through according to its mass.
here H is the Heat energy supplied to the material. m is the mass of the material. c is the specific heat capacity of the material and ∅ is the temperature difference applied to the material. we are given that H= 337,500J , m = 50 kg and ∅ = 15 °C. so from the equation now we can calculate the value of c. after calculating c we can find the material because c is an unique value for a particular material. no two materials have the same c value.
c = 337500/(50*15)
c = 450 J/(kg°C) - Iron (google the heat capacity value to find the answer Iron)
