Answer:

because this is where Arctic air, cold fronts that have not been "weakened". As these fronts head further east, they sometimes lose their strength as they travel over more warm air.

Earth’s axis slowly but continuously points in different directions. True or False
Dafna11 [192]

True

Earth’s axis slowly but continuously points in different directions in a phenomenon called <u>axial precession</u>.

Explanation:

The tilt of the earth is not constant at 23.5 degrees.  Rather the earth's axis precesses in a cycle of approximately 25,772 years. This slow precession can have an apparent effect on climate on earth, especially in conjunction with <em>Milankovitch cycles</em> like aphelion and perihelion. Due to the axial precession, the poles can be facing to or away from the sun during aphelion or perihelion. This consequently can affect the cover ice sheet and glacier in the poles due to the time of exposure to sun rays.

A ball is launched with an initial velocity of 3m/s, at an angle of 40 degrees above the horizontal, and from a height of 0.5m.
Brut [27]

Answer:

The ball travels <u>1.31 m horizontally</u> before hitting the ground.

Explanation:

Given:

Initial velocity of the ball is, u=3\ m/s

Angle of projection is, \theta=40\ degree

Initial height of the ball is, y_0=0.5\ m

Final height of the ball is, y=0\ m

Now, horizontal  and vertical components of initial velocity are given as:

u_x=u\cos\theta\\\\u_y=u\sin\theta

Plug in the given values and find u_x\ and\ u_y. This gives,

u_x=3\ m/s\times \cos(40)\\\\u_x=2.3\ m/s\\\\u_y=3\ m/s\times \sin(40)\\\\u_y=1.9\ m/s

Now, there is acceleration due to gravity acting in the vertical direction. The direction is downward. So, g=-9.8\ m/s^2.

Now, using equation of motion in the vertical direction, we have:

y-y_0=u_yt+\frac{1}{2}a_y t^2

Plug in the given values and solve for time 't'. This gives,

0-0.5=1.9t-0.5\times 9.8\times t^2\\\\-0.5=1.9t-4.9t^2\\\\4.9t^2-1.9t-0.5=0

On solving the above quadratic equation, we get:

t=0.57\ s\ or\ t=-0.18\ s

Ignoring the negative result as time can't be negative. So, time taken by the ball to reach the ground is 0.57 s.

Now, as the ball moves, there is no force acting on it in the horizontal direction. So, the acceleration in the horizontal direction is 0.

Now, we know that, when acceleration is zero, the body moves with a constant speed.

Hence, distance traveled in the horizontal direction is given as:

Horizontal distance = Horizontal component of initial velocity × Time

R=u_x\times t

Plug in the given values and solve for 'R'. This gives,

R=2.3\times 0.57\\\\R=1.31\ m

So, the ball travels 1.31 m horizontally before hitting the ground.

Mark the correct statement: a) Charges flow through a circuit b) voltage is applied across the circuit c) voltage is the ratio o
Gennadij [26K]

Answer:

The correct option is;

d) All of the above

Explanation:

a) In an electric circuit through which electric current flows, it is due to the electric charges which can be the negatively charged electrons or the positively charged protons

b) Voltage is the potential difference that results in current flowing through the circuit, therefore, the voltage is applied across the circuit through which current flows

c) The voltage which is the electric potential difference is the change in potential energy in joules of a given system due to the movement of a test charge (in Coulombs) between points in the electric field, ΔE, divided by the value of the test charge, 'q'

V = ΔE/q

Therefore, all of the above are correct.

What is the density of iron if 5.0 cm3 has a mass of 39.5g
weqwewe [10]

Answer :\rho = 7.9\ g/cm^3

Explanation :

It is given that

Mass of iron, m = 39.5 g

Volume of iron, V = 5\ cm^3

So, density is :

density, \rho =\dfrac{mass}{volume}

\rho =\dfrac{39.5g}{5cm^3}

\rho = 7.9\ g/cm^3
