A particularly long radio wave has a wavelength of 1.5 x 10^9 meters. What is the frequency of this radio wave?

Biology

Phoenix [80]3 years ago
7 0

Answer:

0.2Hz

Explanation:

The wavelength of a radiowave can be calculated this;

λ = v/f

Where;

λ = Wavelength (m)

v = speed (m/s)

f = frequency (Hz)

Based on the information provided in this question, λ = 1.5 x 10^9 meters, c = 3 × 10^8m/s, f = ?

Hence, using λ = v/f

f = v/λ

f = 3 × 10^8 ÷ 1.5 x 10^9

f = 2 × 10^(8-9)

f = 2 × 10^-1

f = 0.2Hz

Whats the relationship between enzymes and sunstrates?
aleksklad [387]

Enzymes and substrates are related in two main ways because they frequently interact with each other in many biological processes.

1. Enzymes and substrates are  often specific for one another. They have shapes that can be modified to fit into each other which allows them to bind together (induced fit).

2. Together, Enzymes and substrates undergo some transformations  as they interact. They interact by forming hydrogen bonds, covalent bonds  and what is also called hydrophobic interactions.

The enzyme returns to its original shape and state after the reaction but the substrate is often modified or changed completely into a new, different product.

Summarize the bonding properties of carbon
notka56 [123]
Well, Carbon has 4 Valence Electrons. I'm sure you know this, but valance electrons allow electrons to covalently bond with one another. The elements, when sharing the electrons, want to have 8 valance electrons. So carbon has 4 valance electrons so it can bond with itself, or another say 4 hydrogen [becuase hydrogen can live with 2 valance electrons]. Hope this helps. Remember: Electrons <3 8 valance electron bonds Carbon's 4 + Carbon's 4= 8 true love at first bond! OR Carbon's 4+ Hydrogen's 1 [x4] = 8 hope this help

Two garden plots were planted with corn. The soil was similar in each, and equal amounts of water were applied to each plot. One
neonofarm [45]

Answer: control plot

Explanation:

Control plot refers to the plot that couldn’t receive the experimental treatment such as fertilizer and or variable being tested while another plot receive fertilizer can give proper yield.  It is just because, fertilizer is the main source or substance that provides chemical elements that may necessary for corn plant growth and its development.  There are two main types of fertilizers such as organic and inorganic, among them organic fertilizer usually contains different nutrients that broken down by different microorganism and then used by such plants to grow effectively.

What happens to the energy that is stored in cells? Check all that apply.
Julli [10]

Answer:

A, D & E

Explanation:   All ATPs are not spent at the same time, and futhermore, they are constantly replaced by the continuous process of cellular respiration that captures the chemical energy in the glucose molecules and stores them in ATP. During the release of this energy to power the biochemical reactions, much of it is lost as heat energy and this is why living organisms are always warm.
