Answer:
v = 2591.83 m/s
Explanation:
Given that,
The electric field is 1.27 kV/m and the magnetic field is 0.49 T. We need to find the electron's speed if the fields are perpendicular to each other. The magnetic force is balanced by the electric force such that,
So, the speed of the electron is 2591.83 m/s.
Gas pressure will also increase then.., if volume is kept constant
We need to learn about median and mode because they are both important in statistical data and statistical data is what shows us important information about the world around us.
The force needed to accelerate a 2500 kg car at a rate of 4m/s² will be 10,000 N.Option B is correct.
<h3>What is force?</h3>
Force is defined as the push or pull applied to the body. Sometimes it is used to change the shape, size, and direction of the body. Force is defined as the product of mass and acceleration. Its unit is Newton.
Given data;
Force,F = ?
Mass,m = 2500 kg
Acceleration,a = 4 m/s²
The force is found as;
F=ma
F=2500 kg × 4 m/s²
F= 10,000 N
The force needed to accelerate a 2500 kg car at a rate of 4m/s² will be 10,000 N.
Hence option B is correct.
