Describe the benefits and risks associated with nuclear energy.

Ulleksa [173]

Producing nuclear energy is far more environmentally friendly than burning fossil fuels. That is the main benefit.

The main risk is radiation. If the nuclear waste is not properly disposed of, it can leak radiation into the environment. Fortunately, this is not an issue since there are ways to deal with it. There is also the risk of a disaster like the Chernobyl incident, however that was mostly due to faulty reactor construction. However, reactors today are built to avoid such issues.

in mammal the weight of the heart approximately 0.5% total body weight write linear model that gives the heart weight in terms o

maks197457 [2]

Let the total weight of the body be = x

Let the weight of the heart of the mammals be = y

Now the given percentage of 0.5 %, we will convert it into decimal form,

so this is equal to 0.005 in decimal form,

so the linear equation that gives the heart weight in terms of body weight will be,

y = 0.005x

Why do baseball pitchers throw the ball at an angle that is slightly above the horizontal if they want the ball to reach at appr

lesantik [10]

Answer:

The angle above the horizontal at which the pitcher throws the ball determines the distance the ball travels before returning to the height at which it was thrown

Explanation:

The baseball is thrown as a projectile and the range, 'R', of the baseball which is the distance the baseball travels before the height above the ground returns to the initial height is given given as follows;

$R = \dfrac{u^2 \cdot sin(2\cdot \theta )}{g}$

Where;

R = The range of the baseball = The horizontal distance away from the pitcher the ball reaches

u = The initial velocity with which the baseball was thrown

θ = The angle above horizontal a baseball pitcher throws the ball

g = The acceleration due to gravity ≈ 9.81 m/s²

From the the equation, when θ = 0, sin(θ) = sin(0) = 0 and the ball does not cover any horizontal distance before going lower than the height at which it was thrown, therefore, for the ball to travel further, the angle of launch, θ has to be larger than 0.
