Answer:

When a underground suddenly breaks along a fault it cause vibration it is called earthquake.

Answer:

Explanation:

Generally, an increase in temperature increases the rate of a chemical reaction. Consequently, when the temperature of a reaction is raised, the molecules present in the reaction interact faster by colliding with one another and surpassing the effective collision of such reaction to bring about a high reaction rate. Similarly, in the case of the rocket launch, the same process occurs as the temperature increase will cause an increase in the reaction rate leading the hydrogen from the acid to react explosively with the oxygen from the base to form water - this makes the rocket defy gravity and launch upward.

Answer:

t = 10 s

Explanation:

Given :

Altitude, h = 490 m

Initial velocity of a plane, u = 250 m/s

To find :

The time required for the packet to hit the ground. When it hits the ground its velocity will be 0. Let t is the required time. It can be calculated as follows :

[tex]t=\sqrt{\dfrac{2h}{g}} \\\\t=\sqrt{\dfrac{2\times 490}{9.8}} \\\\t=10\ s[/tex]

So, it will take 10 s to reach the ground.

Explanation:

Since there are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 365.24 days in a year, then you multiply all of those.

60*60*24*365.24 =

Answer:

a=4,32m/s^2

Explanation:

Fnet = F1 - F2

= 12-1.2

= 10.8N

m=2.5kg

Fnet =ma

10.8=2.5a then divide both sides by 2.5 to get acceleration

Explanation:

Given parameters:

Number of turns in primary coil  = 1000 turns

Primary voltage  = 230V

Secondary voltage  = 46V

Unknown:

Number of turns in secondary coil = ?

Solution:

To solve this problem, we have to use the expression for solving problems related with transformers;

        [tex]\frac{Vs}{Ns}[/tex]   = [tex]\frac{Vp}{Np}[/tex]  

Vs is the secondary voltage

Ns is the number of secondary turns

Vp is the primary voltage

Np is the number of primary turns

 Now insert the parameters and solve;

         [tex]\frac{46}{Ns}[/tex]   = [tex]\frac{230}{1000}[/tex]

          46 x 1000 = 230Ns

             Ns = 200

Answer: The Water

Explanation:

The boiling litre of water has more volume and so has more heated molecules per cubic metre so it will have a higher amount of heat than the glowing nail.

To practically test this, put the glowing nail into a litre of cold water and record the final temperature when the nail has cooled down. Repeat this with the boiling litre of water. You will notice a higher final temperature with the boiling water indicating that it had more heat.

Compound interest:

[tex]a = p( 1 + \frac{r}{n} ) { }^{nt} [/tex]

a = final amount

p = principal amount

r = rate of interest

t = time

n = no. of compounding periods per year

p = 10000

r = 5% = 5/100 = 0.05

t = 2

n = 1

[tex]a = 10000(1 + \frac{0.05}{1} ) {}^{2 \times 1} [/tex]

[tex]a = 10000(1 + 0.05) {}^{2} [/tex]

[tex]a = 10000(1.05) {}^{2} [/tex]

[tex]a = 10000(1.1025)[/tex]

[tex]a = 11025[/tex]

Answer:

because the presure it puts on your body same as if you go to deep in the water

Answer:

In physical changes no new materials are formed and the particles do not change apart from gaining or losing energy. ... Particles stay the same unless there is a chemical change whether the matter is solid, liquid or gas. Only their arrangement, energy and movement changes.

Explanation:

this is true because if you think about it if you put a pill in a glass of water it dissolves its like particles

Explanation:

Named for 19th-century French physicist André-Marie Ampère, it represents a flow of one coulomb of electricity per second.

Answer:

58 g

Explanation:

Momentum = mass* velocity

P=mv

P= 1.06 kg*m/s

M=?

V=18 m/s

1.06 kg*m/s=m(18m/s)

M=0.058 kg

0.058kg = 58 g

Complete question

A cannon with a muzzle velocity of 500. meters per second fires a cannonball at an angle of 30.° above the horizontal. What is the vertical component of the cannonball's velocity as it leaves the cannon?

A   0.0 m/s

B    250. m/s

C   433 m/s

D    500. m/s

Answer:

The correct option is  C

Explanation:

From the question we are told that

   The velocity is  [tex]v = 500 \ m/s[/tex]

    The angle is  [tex]\theta = 30^o[/tex]

Generally the vertical component of the canon ball is mathematically represented as  

          [tex]v_y = v * cos (30 )[/tex]

=>       [tex]v_y = 500 * cos (30 )[/tex]

=>       [tex]v_y = 433 \ m/s[/tex]

Answer:

250. m/s

Explanation:

It is vertical component so you do: 500mSin(30°) = 250m/s

Answer:

1275J

Explanation:

Given parameters:

Force on box  = 85N

Distance moved  = 15m

Unknown:

Work done  = ?

Solution:

Work done is the amount of force applied on a body to move it through a specific distance.

 Work done  = Force x distance

Now insert the parameters and solve;

 Work done = 85 x 15  = 1275J

Answer:

2500kgm/s

Explanation:

Change in momentum is equal to impulse, numerically.

Ft=m( v-u)

But he begins from rest so u= 0

Then

Ft= mv

500(5)=mv

2500= mv

Answer:

24m

Explanation:

Given parameters:

Initial velocity  = 0m/s

Acceleration  = 3m/s²

Time  = 4s

Unknown:

Distance covered  = ?

Solution:

To solve this problem, we apply the right motion equation:

             S = ut + [tex]\frac{1}{2}[/tex]at²

S is the distance

u is the initial velocity

t is the time taken

a is the acceleration;

        S  = (0 x 4) +  [tex]\frac{1}{2}[/tex] x 3 x 4²  

        S = 24m

Answer:

V₂ = 19 [m/s]

Explanation:

The final linear momentum will be equal to the sum of the initial momentum plus the momentum received.  By means of the following equation, we can determine the final momentum.

[tex]m_{1}*v_{1} + IMP_{1-2} = m_{2}*v_{2}[/tex]

where:

m₁ = m₂ = mass = 30 [kg]

v₁ = velocity = 11 [m/s]

IMP₁-₂ = 240 [kg*m/s]

v₂ = final velocity [m/s]

[tex](30*11) + 240 = 30*V_{2}\\330 + 240 = 30*V_{2}\\v_{2}=19 [m/s][/tex]

The final velocity of the object is 19 m/s

The impulse is given by:

Impulse = m(v - u)

where m is the mass, v is the final velocity and u is the initial velocity.

Given that impulse = 240 kgm/s, u = 11 m/s, m = 30 kg. Hence:

Impulse = m(v - u)

240 = 30(v - 11)

8 = v - 11

v = 19 m/s

The final velocity of the object is 19 m/s

Answer:

height = 45 m

Explanation:

Initial velocity = 0 m/s

Final velocity = 30 m/s

Acceleration due to gravity = +10m/s^2 ( because ball is going down )

Using the eqn of motion

[tex] {v}^{2} - {u}^{2} = 2gh[/tex]

where v= final velocity ; u = initial velocity ; g = acceleration due to gravity ; h = height

So,

[tex] {30}^{2} - {0}^{2} = 2 \times 10 \times h[/tex]

[tex] = > 20h = 900[/tex]

[tex] = > h = \frac{900}{20} = 45[/tex]
