1. What is the pressure caused on the ground by an elephant of weight 20000N

Define "increased productivity" in terms of the number of tasks and the amount of time.

vovikov84 [41]

Answer:

The greater the amount of output for a given unit of input, the higher the overall productivity. Businesses generally aim to improve productivity over time to maintain competitiveness and increase the business's profitability. Individuals are familiar with the idea of productivity in their own lives.

Calculate the equivalent resistance for both circuits.

Allisa [31]

Answer:

Series equivalent resistance: $R_{eq} = 6 \Omega$

Parallel equivalent resistance: $R_{eq}=14\Omega$

Explanation:

The equivalent resistance in series circuit is calculated as

$R_{eq} = R_{1} + R_{2}$

$R_{eq} = 2 + 4$

$R_{eq} = 6 \Omega$

The equivalent resistance in parallel circuit is calculated as

$\frac{1}{R_{eq}} = \frac{1}{R_{1}}+\frac{1}{R_{2}}$

Which can be simplified to

$R_{eq}=\frac{R_{1}\times R_{2}}{R_{1}+R_{2}}$

$R_{eq}=\frac{21\times 42}{21+42}$

$R_{eq}=14\Omega$

The parallel circuit has the higher equivalent resistance as compared to series circuit.

The siren on an ambulance is emitting a sound whose frequency is2550 Hz. The speed of sound is 343 m/s.(a) If the ambulance is s

Sati [7]

Answer:

0.13451 m

0.124196 m

0.119997901132 m

Explanation:

$v_o$ = Velocity of the observer

$v_s$ = Velocity of sound source

v = Velocity of sound in air = 343 m/s

Wavelength is given by

$\lambda=\dfrac{v}{f}\\\Rightarrow \lambda=\dfrac{343}{2550}\\\Rightarrow \lambda=0.13451\ m$

The wavelength is 0.13451 m

From Doppler effect we have the formula

$f=f'\dfrac{v}{v-v_s}\\\Rightarrow f=2550\dfrac{343}{343-26.3}\\\Rightarrow f=2761.7619198\ Hz$

$\lambda=\dfrac{343}{2761.7619198}\\\Rightarrow \lambda=0.124196\ m$

The wavelength is 0.124196 m

$f=f'\dfrac{v+v_o}{v-v_s}\\\Rightarrow f=2550\dfrac{343+12}{343-26.3}\\\Rightarrow f=2858.38332807\ Hz$

$\lambda=\dfrac{343}{2858.38332807}\\\Rightarrow \lambda=0.119997901132\ m$

The wavelength is 0.119997901132 m

do you think the a black hole is a hole in between time and space and that is the answer to time travel

Tanzania [10]

A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it. Or survive butttttt we could never know unless we go through ourselves
