b. covalent bond
c. iconic bond
Answer:
In ionic compounds, electrons are transferred between atoms of different elements ... For example, two hydrogen atoms bond covalently to form an H2 molecule; each ... is released when one mole of H2 molecules forms from two moles of H atoms: ... atom in each pair is more electronegative: (a) N or P. (b) N or Ge. (c) S or F.
Explanation:
b. 11 kg.
c. 110 kg.
d. 1100 kg.
e. none of the above
A lamb that weighs 110 N has a mass of around 11 kg. Hence, option B is correct except B all options are incorrect.
The mass of a physical body is a measure of its entire makeup. Inertia, or the body's resistance to acceleration when a net force is applied, is also measured by this term. The strength of a body's gravitational pull on other bodies is also influenced by its mass. The kilogram is the fundamental mass unit of the SI.
In physics and engineering, the weight of an object refers to the gravitational force that pulls on it. Weight is the term used in many widely used textbooks to describe the gravitational force acting on the object. Some people think of weight as a scalar quantity that gauges the gravitational force's strength.
According to the question, the given values are :
Weight, w = 110 N and,
Taking value of g = 10 m/s²
As we know that :
w = m × g
110 = m (10)
m = 11 kg
Hence, the mass of the lamb will be 11 kg.

I'll report you if you don't actually help. I'd like an actual explanation, please.
Hey
So first we need to know what the direction of the force is, using your right hand rule point your right hand in the direction of the velocity. You're saying its the z direction, not telling me whether it's into the page or out? Since its a positive z im assuming its coming out. The magnetic field is pushing it upwards, so the force is going in the negative x direction.
The force of a magnetic field is
F = Qv X B
What's weird is that you don't need mass in this equation. Actually you don't even need the formula, its telling you that they're all going in perpendicar directions. the answer is 90 degrees.
Now if you want to know the F just multiply the charge, velocity and magnetic field .
F = GVB
F = 6.048 E -15
Answer : 90 degrees, sin(90) = 1
To find the magnitude and direction of the magnetic force on a proton moving in a magnetic field, you can use the equation F = qvBsinθ, where F is the force, q is the charge, v is the velocity, B is the magnetic field, and θ is the angle between the velocity and the magnetic field. The magnitude of the magnetic force can be calculated using the equation, and its direction can be determined using the right-hand rule. In this case, the angle between the proton's velocity and the magnetic field is 90°.
To determine the magnitude of the magnetic force on the proton, we need to use the equation F = qvBsinθ, where F is the force, q is the charge, v is the velocity, B is the magnetic field, and θ is the angle between the velocity and the magnetic field.
Plugging in the values, we have F = (1.6 × 10-19 C)(1.8 × 105 m/s)(2.1 × 10-1 T)sinθ.
To find the angle θ, we can use the fact that the force is perpendicular to both the velocity and the magnetic field, which means that sinθ = 1.
Therefore, the magnitude of the magnetic force on the proton is F = (1.6 × 10-19 C)(1.8 × 105 m/s)(2.1 × 10-1 T) = 6.048 × 10-14 N. The direction of the magnetic force is given by the right-hand rule, which shows that the force is perpendicular to both the velocity and the magnetic field, pointing in the positive x-direction.
The angle between the proton's velocity and the magnetic field is 90°.
