A boat moves initially at 10 m/s, then accelerates at 2 m/s^2 for 10 s. What is the velocity of the boat after 10 s?

Physics
1 answer:
Fudgin [204]3 years ago

Answer:

30 m/s

Explanation:

A boat moves initially at 10 m/s

The boat accelerates at 2 m/s^2 for 10 seconds

We are required to calculate the final velocity (v)

Therefore the velocity of the boat can be calculated as follows

v = u + at

u= 10 m/s

a= 2 m/s^2

t= 10 seconds

v= 10 + 2(10)

v= 10 + 20

= 30 m/s

Hence the velocity of the boat after 10 seconds is 30 m/s

Decomposition reactions are said to be those reactions in which a reactants breakdown into two or more products. The general reaction for decomposition reactions is as follow,

                                         ABC    →    A  +  B  +  C

Specific Examples are as,

                                Water    →     Hydrogen + Oxygen

                                2 H₂O    →           2 H₂     +      O₂

               Calcium carbonate    →     Calcium oxide + Carbon dioxide

                            CaCO₃              →              CaO         +        CO₂

While, Synthetic reactions are said to be those reactions in which two or more reactants combine to form two or more products. The general reaction for synthetic reactions is as follow,

                                         A  +  B  +  C    →    ABC

Specific Examples are as,

                                  Iron + Oxygen     →     Iron Oxide

                                    2 Fe  +  3 O₂      →        2 Fe₂O₃

                          Sodium + Chlorine     →     Sodium chloride

                              2 Na  +       Cl₂        →            2 NaCl

                            Sulfur + Oxygen      →      Sulfur dioxide

                                  S    +    O₂            →             SO₂

                   Potassium + Chlorine      →      Potassium chloride

                            2 K     +     Cl₂            →              2 KCl

A step up transformer has 250 turns on its primary and 500 turns on it secondary. When the primary is connected to a 200 V and t
Zina [86]

Answer:

2000 W

Explanation:

First of all, we need to find the output voltage in the transformer, by using the transformer equation:

\frac{V_1}{N_1}=\frac{V_2}{N_2}

where here we have

V1 = 200 V is the voltage in the primary coil

V2 is the voltage in the secondary coil

N1 = 250 is the number of turns in the primary coil

N2 = 500 is the number of turns in the secondary coil

Solving for V2,

V_2 = N_2 \frac{V_1}{N_1}=(500) \frac{200 V}{250}=400 V

Now we can find the power output, which is given by

P = VI

where

V = 400 V is the output voltage

I = 5 A is the output current

Substituting,

P = (400 V)(5 A) = 2,000 W

an electron travels at 0.3037 times the speed of light through a magnetic field and feels a force of 1.2498 pN. What is the magn
ahrayia [7]

Answer:

Explanation:

Charge on an electron (q) = 1.6 * 10 ^ -19 C

Velocity of electron (v) = 0.3037 * 300,000,000 = 91,110,000 m/sec

We know that, Force exerted on moving particle moving through a magnetic field :

F= q * v * B ( q,v\ and\  B\ are\ mutually\ perpendicular)

1.2498 * 10 ^ -12 = 1.6 * 10^ -19 * 91110000 * B

B =  0.08573 T

At which position is the LOWEST potential energy?
Ad libitum [116K]
The answer is position 3, because it is at its lowest point.

Potential Energy is “stored energy.” It is energy that is ready to be converted or released as another type of energy. We most often think of potential energy as gravitational potential energy. When objects are higher up, they are ready to fall back down. When you stretch an object and it has a tendency to return to its original shape, it is said to have elastic potential energy. Chemical potential energy is the stored energy in a substance’s chemical structure that can be released in a chemical reaction or as heat.
