Answer:
P = 4000 [Pa]
Explanation:
Pressure is defined as the relationship between Force and the area where the body rests.
The support area is equal to:
![A=50*20=1000[cm^{2} ]](https://tex.z-dn.net/?f=A%3D50%2A20%3D1000%5Bcm%5E%7B2%7D%20%5D)
But we must convert from square centimeters to square meters.
![1000[cm^{2}]*\frac{1^{2}m^{2} }{100^{2}m^{2} }=0.1[m^{2} ]](https://tex.z-dn.net/?f=1000%5Bcm%5E%7B2%7D%5D%2A%5Cfrac%7B1%5E%7B2%7Dm%5E%7B2%7D%20%20%7D%7B100%5E%7B2%7Dm%5E%7B2%7D%20%20%7D%3D0.1%5Bm%5E%7B2%7D%20%5D)
And the pressure is:
![P=\frac{F}{A} \\P=400/0.1\\P=4000[N/m^{2} ]or 4000[Pa]](https://tex.z-dn.net/?f=P%3D%5Cfrac%7BF%7D%7BA%7D%20%5C%5CP%3D400%2F0.1%5C%5CP%3D4000%5BN%2Fm%5E%7B2%7D%20%5Dor%204000%5BPa%5D)
Answer:
130m/s^2 and 1.22s
Explanation:
From V = u+at
Where V, u, a, and t are the final velocity, initial velocity, acceleration and time respectively.
v = 6.75m/s
u = 3.5m/s
t = 0.250secs
a = ?
V = u+at
6.75= 3.5+a(0.250)
6.75-3.5 = 0.250a
3.25=0.250a
Divide both sides by 0.250
3.25/0.250= 0.250a/0.250
a = 130m/s^2
The acceleration of the will be 130 meter per second
Question 2
Speed = distance/time
Given that speed= 4.25m/s
Distance = 5.2m and time = ?
4.25m/s = 5.2m/t
Cross multiply
4.25×t = 5.2
Make t the subject by dividing both sides by 4.25
4.25t/4.25 = 5.2/4.25
t = 1.22s
Hence the time taken will be 1.22 seconds
Answer:
RESISTANCE
Explanation:
A multimeter or multitester is a measuring instrument that can measure multiple electrical properties. A typical multimeter can measure voltage, resistance, and current, in which case it is also known as a volt-ohm-milliammeter.
The answer is that they are altogether different. In a colloid, there is no necessity that the scattered gold be as disengaged iotas. Colloidal gold is as nanoparticles, each having numerous iotas of gold. Note that gold is normally monoatomic, and does not tie to itself synthetically, not at all like oxygen, which ties in sets to accomplish lively soundness.
A dark-colored (igneous rock,) commonly extrusive from volcanic eruptions and composed primarily of the minerals of calcic plagioclase and pyroxene, and sometimes olivine. Basalt is the fine-grained equivalent of gabbro.
