Answer:
B. 0.50 meters/second^2
Explanation:
Given:
- mass of table (m) = 10.0 kg
- Eli's force (F1) = 120 N
- Andy's force (F2) = -125 N
Arranging Formulas and Substituting Values, Part 1:
- F = F1 + F2
- F = 120 + (-125)
- F = -5 N
- The -5 means that the table will move along the direction of the force applied by Andy.
Arranging Formulas and Substituting Values, Part 2:
- m * a = F
- a = F / M
- a = -5 / 10.0 kg
- a = -0.5 m/s^2
Answer:
To derive the fourth equation of motion, first we have to consider the equation for acceleration and then to rearrange it. or v2 = u2 + 2as and this equation of motion can be used to find the final velocity or the distance travelled if the other values are given.
Explanation:
v= u + at
s =( u + v ) t /2
s = ut + at2/2
v2 = u2 + 2as
Answer:Thermal energy is a measure of a substance 's specific heat
Explanation:
CORRECT ANSWER:
a- Cell-surface receptors bind polar signaling molecules; intracellular receptors bind nonpolar signaling molecules.
STEP-BY-STEP EXPLANATION:
The complete question from book is
According to Figure 9.6, what is a key difference between cell signaling by a cell-surface receptor and cell signaling by an intracellular receptor?
a- Cell-surface receptors bind polar signaling molecules; intracellular receptors bind nonpolar signaling molecules.
b- Signaling molecules that bind to cell-surface receptors lead to cellular responses restricted to the cytoplasm; signaling molecules that bind to intracellular receptors lead to cellular responses restricted to the nucleus.
c- Cell-surface receptors bind to specific signaling molecules; intracellular receptors bind any signaling molecule.
d- Cell-surface receptors typically bind to signaling molecules that are smaller than those bound by intracellular receptors.
e- None of the other answer options is correct.
When a proton is fired without any positive or negative forces within the grid the proton will pass straight through the grid without changing its path. A proton is a subatomic particle found in the nucleus of every atom. The particle has a positive electrical charge, equal and opposite to that of the electron. If isolated a single proton would have a mass of 1.673 × 106-27 kg which is slightly less than that of a neutron.
