Answer:

466J

Explanation:

Given parameters:

Mass of steel = 1kg = 1000g

Initial temperature = 21°C

Final temperature = 22°C

Unknown:

Amount of heat required for this temperature increase = ?

Solution:

To solve this problem, we use the expression below:

So;

Heat absorbed = mass x specific heat of steel x change in temperature

Specific heat of steel = 0.466J/g°C

Therefore;

Heat absorbed = 1000 x 0.466 x (22 - 21) = 466J

The answer is B. Vas deferens.

The Vas deferens is a tube that carries the sperm from your testes to the urethra and out the body. A vasectomy is a form of birth control where the pathway of sperm is blocked through cutting or tying off the vas deferens. The word Vasectomy comes from the term Vas<span> deferens.</span>

If a 4N weight is hung on a spring, and it extends by 0.2m, what is the spring constant (k)?

Naddika [18.5K]

Answer: 200 N/m

Explanation:

The Gravitational spring energy(Us) is equal to 1/2kx^2. So we have x as .2 m and Us as 4 N. So 4 N = 1/2 * k * .2^2. So now we solve for K and get 200 N/m.

An 89 kg man drops from rest on a diving board −3.1 m above the surface of the water and comes to rest 0.5 s after reaching the

OLga [1]

To solve this problem we will use the linear motion kinematic equations, for which the change of speed squared with the acceleration and the change of position. The acceleration in this case will be the same given by gravity, so our values would be given as,

$m= 89 kg\\x = 3.1 m\\t = 0.5s\\a = g = 9.8m/s^2$

Through the aforementioned formula we will have to

$v_f^2-v_i^2 = 2ax$

The particulate part of the rest, so the final speed would be

$v_f^2 = 2gx$

$v_f=\sqrt{2(9.8)(3.1)}$

$v_f = 7.79m/s$

Now from Newton's second law we know that

$F = ma$

Here,

m = mass

a = acceleration, which can also be written as a function of velocity and time, then

$F = m\frac{dv}{dt}$

Replacing we have that,

$F = (89)\frac{7.79}{0.5}$

$F = 1386.62N$

Therefore the force that the water exert on the man is 1386.62

How does competition affect population size? Use the terms carrying capacity and limiting factor with your example.

svetoff [14.1K]

Limiting factors are resources or other factors in the environment that can lower the population growth rate. Competition for resources like food and space cause the growth rate to stop increasing, so the population levels off. This flat upper line on a growth curve is the carrying capacity.
