When choosing a protein it is best to choose one for high in saturated fats true or false​

Physics
1 answer:
Elena L [17]3 years ago
5 0

Answer:

False

Explanation:

When choosing a protein, it is not best to choose one high in saturated fats. Saturated fats include foods like lard and butter. Eating too much animal fat (saturated fats) over time could increase the chances of a heart disease. Lipids, an energy source for cells, will begin to build up in the walls of blood vessels. This will eventually reduce blood flow and increase a persons risk of getting a heart attack.

The position-time equation for a cheetah chasing an antelope is:
pochemuha

Answer:

x = 1.6 + 1.7 t^2      omitting signs

a) at t = 0     x = 1.6 m

b) V = d x / d t = 3.4 t

at t = 0     V = 0

c) A = d^2 x / d t^2 = 3.4     (at t = 0  A = 3.4 m/s^2)

d)  x = 1.6 + 1.7 * (4.4)^2 = 34.5    (position at 4.4 sec = 34.5 m)

The spring is unstretched at the position x = 0. under the action of a force p, the cart moves from the initial position x1 = -8

</span>
Solution:
(a) The work done by the spring is given by
W= \frac{1}{2} k (\Delta x)^2 &#10;
where k is the elastic constant of the spring and \Delta x is the stretch between the initial and final position. Since x1=-8 in=-0.203 m and x2=5 in=0.127 m, we have
W= \frac{1}{2} \cdot 500 N/m \cdot (0.127m-(-0.203m))^2=27.25 J

(b) The work done by the weight is the product of the component of the weight parallel to the inclined plane and the displacement of the cart:
W_W = -F_{//} (x_2 -x_1)
where  the negative sign is given by the fact that F_{//} points in the opposite direction of the displacement of the cart, and where
F_{//}=m g sin 15^{\circ}=6 kg \cdot 9.81m/s^2 \cdot sin 15^{\circ}=15.2 N
therefore, the work done by the weight is
W_W=-15.2 N \cdot (0.203m-(-0.127m))=-5.02 J
