To investigate seed growth in different levels of light, Jarrod covers seeds with soil in three different containers. He places

a pea seed in a short, wide plastic cup, a cucumber seed in tall, skinny glass, and a tomato seed in a shallow, plastic dish. He places the plastic cup in a window sill in direct sunlight, the glass outside in partially shaded area, and the dish in his closet in the dark. He will leave the containers in those places for one week, and record the growth at the end of his investigation. How could Jarrod's investigation be adapted to create a fair test

Jarrod could have the same types of seeds because different seedgrow at different rates. He could also use the same type of dish.

To make his investigation a fair test, he should test the same type of seed in the same type and size cup. By making all other parts of his investigation the same, he can study one variable.

<span>Acceleration is the rate of change of the velocity of an object that is moving. This value is a result of all the forces that is acting on an object which is described by Newton's second law of motion. Calculations of such is straightforward, if we are given the final velocity, the initial velocity and the total time interval. However, we are not given these values. We are only left by using the kinematic equation expressed as:

d = v0t + at^2/2

We cancel the term with v0 since it is initially at rest,

d = at^2/2
44 = a(6.2)^2/2
a = 2.3 m/s^2

An electric field of magnitude 2.35 V/m is oriented at an angle of 25.0° with respect to the positive z-direction. Determine the
zzz [600]

Answer:

The magnitude of the electric flux is 3.53\ N-m^2/C

Explanation:

Given that,

Electric field = 2.35 V/m

Angle = 25.0°

Area A= 1.65 m^2

We need to calculate the flux

Using formula of the magnetic flux

\phi=E\cdot A

\phi = EA\cos\theta

Where,

A = area

E = electric field

Put the value into the formula

\phi=2.35\times1.65\times\cos 25^{\circ}

\phi=2.35\times1.65\times0.91

\phi=3.53\ N-m^2/C

Hence, The magnitude of the electric flux is 3.53\ N-m^2/C

Newton's first law equations like velocity and stuff like that
Klio2033 [76]

Answer:

Newton's first law: An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force. ... An object sliding across a table or floor slows down due to the net force of friction acting on the object.
