Answer:
<h3>How did scientists “discover” Pangea and other supercontinents of the past?</h3>
Nowadays, they can study the geologic record and use radioactive dating, seismic surveys, and other technologies to construct maps of how the world looked at various points in Earth's history.
The purpose of the fraud fighter or also known as black
light machine is that it has the ability to check counterfeited bills. It is
designed to be a detector with the counterfeited bills, plus, it is a way of
verification. It is composed of a UV light, where in, making it have the
ability to detect the counterfeited bills which is its task to do.
Answer:
Supercells
Explanation:
supercells are rotating thunderstorms that has a well-defined radar circulation called a mesocyclone. They can sometimes produce destructive hail, severe winds, frequent lightning, and flash floods.
Answer:
No, it is impossible
Explanation:
Kinematics equation:
if height is maximum:
y=H and Vf=0
so:
<h3>
</h3><h3>
</h3>
Analysis: From the last equation we see that the maximum height depends ONLY on the initial speed. This means that if both objects reach the same maximum height, then they necessarily need to have the SAME initial velocity. If they have the same initial velocity and in order to reach the maximum height at the SAME time the only way is that they are released at the SAME TIME.
Answer:
3600 kg
Explanation:
From the question,
Density = Mass/Volume
D = M/V.............................. Equation 1
Where D = Density of the substance, M = mass of the substance, V = Volume of the subtance.
Make M the subject of the equation
M = D×V ............................ Equation 2
Given: D = 1200 kg/m³, V = 3 m³.
Substitute these values into equation 2
M = 1200×3
M = 3600 kg.
Hence the mass of the substance is 3600 kg
