Answer:
Explanation:
Let mass and velocity of proton be m and v .
1/2 m v² = 59 x 10⁶ e V
= 59 x 10⁶ x 1.6 x 10⁻¹⁹ J
= 94.4 x 10⁻¹³ J
mv² = 188.8 x 10⁻¹³ J
v² = 188.8 x 10⁻¹³ / m
= 188.8 x 10⁻¹³ / 1.67262 x 10⁻²⁷
= 112.8768 x 10¹⁴
v = 10.62 x 10⁷ m / s
In circular path of proton , magnetic force equals centripetal force .
m v² / r = B q v , B is magnetic field , q is charge on proton , r is radius of circular path .
188.8 x 10⁻¹³ / 5.8 x 10¹⁰ = B x 1.6 x 10⁻¹⁹ x 10.62 x 10⁷
B = 1.9157 x 10⁻¹¹ T.
Answer:
<h3>The answer is 180 m</h3>
Explanation:
The distance covered by an object given it's velocity and time taken can be found by using the formula
distance = velocity × time
From the question we have
distance = 1.5 × 120
We have the final answer as
<h3>180 m</h3>

Answer:
Volume = 2m³
Explanation:
The pressure of a gas is inversely proportional to its volume when its temperature is constant.
P₁V₁ = P₂V₂
V₂ = (P₁V₁) / P₂
V₂ = (4atm x 0.5m³) / 1atm
V₂ = 2 m³
Answer:B=Negative C=Positive D=Positive
Explanation:objects that repel each other means they have the same polarity. objects that attract have the opposite polarity A is negatively charged if A and B repel then A and B are both negative. B is negatively charged if B and C attract then they have reverse polarity which makes C positively charged. C is positive if C and D repel then that means that C and D have the same polarity making D positively charged.
Speed and tangential acceleration is zero are constant in uniform circular motion
<h3>Further explanation
</h3>
Uniform circular motion is the motion of an object in a circle at a constant speed.
An object moving in uniform circular motion is moving around the circle perimeter with a constant speed. While the speed of the object is constant, its velocity is changing. Velocity, being a vector, has a constant magnitude but a changing direction. Wheres the the tangential component of acceleration is zero in a uniform circular motion. But its value is not zero in a non uniform circular motion.
In uniform circular motion, it is results in change of velocity (velocity has two components such as speed and direction). Because the velocity changes, the acceleration exists. The direction of acceleration in this case is radial, tangential component is zero so the speed is not varying with time. Acceleration exists because of the change in direction of particle’s velocity.
Tangential acceleration quantities are zero throughout the motion. Since a uniform motion itself defines to be a constant velocity motion in which the rotation is going on at a constant speed, the tangential component of acceleration is zero.
