Answer:
Magnitude
Explanation:
Scalar quantitys have no direction only a size aka magnitude
Answer:
Center of mass
Explanation:
The Doppler technique is a good method for discovering exoplanets. It uses the Doppler effect to analyze the motion and properties of the star and planet. Both the planet and the star are orbiting a common center of mass. This means that the star and the planet gravitationally attract one another, causing them to orbit around a point of mass central to both bodies.
Question 1: A) Bicep
Question 2: True
Answer:
Magnetic field, B = 1.9232 T
Explanation:
Given data:
Value of the charge, Q = 0.026 C
Speed, V = 443.592 m/s
Force experienced, F = 22.182
Now,
the Force (F) experienced by a charge in a magnetic field is given as:
F = QVBsinθ
where,
B is the magnetic field
Angle between the magnetic field and the velocity.
since, the velocity is in horizontal direction and the magnetic field is downwards. Therefore, the angle θ = 90°
thus, we have
22.182 = 0.026 × 443.592 × B × sin90°
or
B = 1.9232 T
