Answer:
Distance travel s = 296.8 m
Explanation:
Given:
Initial velocity u = 6.5 m/s
Constant acceleration a = 2.1 m/s²
Time T = 14 s
Find:
Distance travel s
Computation:
s = ut + (1/2)at²
s = (6.5)(14) + (1/2)(2.1)(14)²
s = 91 + 205.8
Distance travel s = 296.8 m
Answer: 26.6 J
Explanation:
The heat needed to raise the temperature of a solid body, using only a conductive process, has been empirically showed to be equal to the following expression:
Q= c . m. (t2 – t1)
where c= specific heat capacity (in J/gK), m= mass of the solid (in g) ,
and (t2 - t1)= difference between final and initial temperatures.
Replacing by the values, we get:
Q= 0.385 J/gK . 1,550 g. (77.5ºC – 33.0ºC)= 26.6 J
Answer:
there are no mutiple choices
The most likely event to occur due to the interaction between the Earth's magnetic field and charged particles blowing away from the sun would be "B. auroras are visible at the poles". The auroras form when when charged particles which are emitted from the sun enter the Earth's magnetic shield and collide with atoms in our atmosphere.
Answer:
V= C√p/s
Explanation:
We are given that
Dimension of speed of sound
V = L T ^-1
Volume of gas = L³
Pressure P= M¹L^-1T^-2
Density =M¹L^-3
So
LT^-1 = C [M¹L^-1T^-2]^x [M¹L^-3]^y [L³]^z
Compare powers
We have
x+y=0
-x+3y+3z=1
-2x=-1
So x= 1/2 y= -1/2 z= 0
So finally we substitute in
V=cp^xp^y V^z
We have
V= C√p/s
