Answer:A projectile attains its maximum height when the angle of projection is. Question. A projectile attains its maximum height when the angle of projection is.
Explanation:
Answer:
Acceleration increases if force applied increases
Acceleration decreases if mass of the object increases
Explanation:
The relationship between mass, acceleration and force applied on an object is described by Newton's second law:
where
F is the net force applied
m is the mass of the object
a is the acceleration
We can rewrite the equation as
So we notice that:
1) acceleration is proportional to the force: therefore, if the force applied increases, the acceleration increases as well
2) acceleration is inversely proportional to the mass: therefore, if the mass of the object increases, the acceleration will decrease
Answer:
I think c is correct options....
Explanation:
The resistance of the wire increases with increase in temperature. The resistance does not depend on the weight of the wire. Therefore, the correct option is weight.
Answer:
a) 0.069 acres
b) 0.114acres
c) 17.78acres
Explanation:
1 dot=1/36sqin
a) 1 sqin= 330×330=108900ft^2
1 dot=108900/36 =3025ft^2
Converting to acre,divide by43560
3025/43560 =0.069acre
b) 1 chain =22 yards
25×22=550yards
Converting to acre divide by 4840
550/4840 =0.114acre
c)1 sqmile =640acres
(1/36) ÷ 640
640/36
17.78acres
When it comes to wave behavior, there are parameters called wavelength and frequency. These two are related by speed of the radiowave. Radiowaves are electromagnetic waves which travels as fast as light. The wavelength is the distance while frequency is the reciprocal of time. When you multiply them both, you get the electromagnetic wave's speed. The equation is c = wavelength*frequency, where c is the speed of light equal to 3 x 10^8 m/s.
3 x10^8 m/s = wavelength/104.9 x 10^6 Hz (Hertz is 1/s)
wavelength = 2.86 meters
