Answer:
70,100 m/s
Explanation:
Given:
v₀ = 205 m/s
a = 8.03 m/s²
Δx = 1750 m
Find: v
v² = v₀² + 2aΔx
v² = (205 m/s)² + 2 (8.03 m/s²) (1750 m)
v = 70,130 m/s
Rounding to three significant figures, the final velocity is 70,100 m/s.
Answer:
Yes the ramp can be safely used
Explanation:
Here, we have
Length of longest ramp = 5 ft
Height of wall = 2 ft
Therefore, the sine of the angle adjacent to the ramp which is equal to the angle of elevation is given by;
Where:
The opposite side to angle = 2 ft wall and
Hypotenuse side = Ramp = 5 ft
Therefore,
and θ = sin⁻¹0.4 = 23.55 °
The ramp can be safely used as the angle it is adjacent to is less than the specified 30°.
1. Scientists are responsible for removing plasmids, small rings of DNA, from bacterial cells.
2. The Enzymes cut open the plasmid DNA. The same enzyme removes the human insulin gene from its chromosome.
3. The human insulin gene attaches the open ends of the plasmid to form a closed ring.
4. Some bacterial cells take up the plasmids that have the insulin gene.
<span>
5. When cells reproduce, the news cells will contain copies of the engineered plasmid. The foreign gene directs the cell to produce human insulin.</span>
FORCE ACTING ON THE BODY , F = 200N
AREA ON WHICH THE FORCE IS ACTING , A = 0.05 CM²
= 0.05*(10⁻²)
= 0.05*10⁻² M²
TO CONVERT CM TO M * BY 10⁻²
PRESSURE = FORCE / AREA
PRESSURE = 200/0.05*10⁻⁴
= 200*10⁴/0.05
= 200*10⁴*10²/5
= 20*10⁵/5
= 4*10⁵ N/M².
HOPE THIS HELPS.
