A scientist wants to study the effects of morning temperatures on flower width. Which is most likely a source of error in this s
ratelena [41]
<span>The flower width data were collected at about the same time every day. </span>  

According to the research, the responder made with the same query as this question it is: <span><span>

1.        </span>The flower width data were collected at about the same time every day. </span>
Why this choice because, the study is delving into the effects of morning temperatures on flower width hence, if the scientists collect flower at the same time –hour or minutes everyday during the period of the study the variable of time is not allotted from sunrise period to high noon since it defines time as morning, the variant of time is only inapt.

Describe the energy changes that take place as the bob of a simple pendulum makes one complete oscillation, starting at its maxi
Monica [59]

Answer:

Gravitational potential energy to kinetic energy to gravitational potential energy to kinetic energy to gravitational potential energy.

Explanation:

Starting at its maximum displacement the pendulum will have only gravitational potential energy, its velocity being 0m/s. When released, it will lose height, losing then gravitational potential energy as it gains speed, or kinetic energy. When the pendulum is at its lowest the gravitational potential energy will be at its minimum and the kinetic energy at its maximum (and so its speed), with value equal to the original gravitational potential energy. Then it starts gaining height again, reverting this process, gaining gravitational potential energy and losing kinetic energy until the velocity is 0m/s again, thus returning to the state of maximum gravitational potential energy (same as originally) and null kinetic energy, but on the opposite side of the oscillation. Then the pendulum comes back repeating the exact same process just descibed, until it finishes one oscillation when reaching the original point.

Two pro baseball players of the same height are testing how far they can throw. One players throws the ball at a 40.0 degrees an
Viktor [21]

Answer:

The  distance traveled by the ball before it lands in the other player's glove is 130.96 m.

Explanation:

Given;

angle of projection of the ball, θ = 40⁰

initial velocity of the ball, u = 36.1 m/s

The distance traveled by the ball before it lands in the other player's glove is the range of the projectile, calculated as follows;

R = \frac{u^2 sin(2\theta)}{g} \\\\R= \frac{36.1^2 \times sin(2\times 40)}{9.8} \\\\R = \frac{36.1^2 \times sin(80)}{9.8} \\\\R = 130.96 \ m

Therefore, the  distance traveled by the ball before it lands in the other player's glove is 130.96 m.
